Attrition bias due to amount, nature or handling of incomplete outcome data. <br /><span style='color: blue;'>NO (low RoB)<span style='color: black;'> if limited loss of data (between enrolled and analyzed). Operationally, we define as <20% loss-to-followup (see caveat under "high").

7. Cochrane - SELECTIVE REPORTING (reporting bias)

<span style='color: blue;'>NO (low RoB): <span style='color: black;'>There is low risk of reporting bias if the study protocol is available and all of the study’s pre-specified (primary and secondary) outcomes that are of interest in the review have been reported in the pre-specified way, or if the study protocol is not available but it is clear that the published reports include all expected outcome, including those that were pre-specified (convincing text of this nature may be uncommon). <br /><span style='color: red;'>YES (high RoB): <span style='color: black;'>There is a high risk of reporting bias if not all of the study’s pre-specified primary outcomes have been reported; one or more primary outcomes is reported using measurements, analysis methods or subsets of the data (e.g. subscales) that were not pre-specified; one or more reported primary outcomes were not pre-specified (unless clear justification for their reporting is provided, such as an unexpected adverse effect); one or more outcomes of interest in the review are reported incompletely so that they cannot be entered in a meta-analysis; the study report fails to include results for a key outcome that would be expected to have been reported for such a study.<br /><span style='color: orange;'>UNSURE<span style='color: black;'> if no protocol or otherwise cannot tell. <br /><span style='color: brown;'>NB:<span style='color: purple;'>1) Answer for all study designs.

9. ROBINS-I 1.1 Is there potential for confounding of the effect of intervention in this study?

For RCT: <span style='color: blue;'>NO (low RoB)<span style='color: black;'> unless there is a <span style='color: red;'>clinically important baseline difference<span style='color: black;'> in a characteristic that is unaccounted for.<br />
For NRCS:<span style='color: red;'> YES<span style='color: black;'> except possibly in rare situations, such as when studying harms that are very unlikely to be related to factors that influence treatment decisions, no confounding is expected and the study can be considered to be at low risk of bias due to confounding, equivalent to a fully randomized trial. <br /><span style='color: blue;'>
If no risk of confounding, then skip to Question 7 (overall confounding RoB).


Value:	Yes No Unsure No Data Not Applicable Other (please specify):
Notes:

10. ROBINS-I 1.2 (variant) Time-varying confounding (crossover)?

Could (or did) participants cross-over between intervention groups after the start of the intervention?

Value:	Yes No Unsure No Data Not Applicable Other (please specify):
Notes:

11. ROBINS-I 1.4. Did the authors fail to use a propensity-score type analysis method that best controlled for all the important confounding domains?

For NRCS (or RCT requiring adjustment):  <br />
<span style='color: red;'>YES (higher RoB):<span style='color: black;'> used stratification, regression, or matching. <br />
<span style='color: blue;'>NO (lower RoB):<span style='color: black;'> used propensity score matching (aka inverse probability weighting) or similar.<br />
<span style='color: purple;'>REJECT if NRCS with no adjustment for confounding

Notes:

12. ROBINS-I 1.5. If Y/PY to 1.4: Were confounding domains that were controlled for not measured validly and reliably by the variables available in this study?

Appropriate control of confounding requires that the variables adjusted for are valid and reliable measures of the confounding domains. 
<br /><span style='color: blue;'>NO (low RoB)<span style='color: black;'> if objective or standard clinical measures (eg, age, sex, time since surgery, duration of osteoarthritis). Also <span style='color: blue;'>NO<span style='color: black;'> if validated subjective measure. For this purpose, we can assume any typically used or named/acronym'ed measure (eg, of severity of osteoarthritis or function) has been validated.<br /><span style='color: red;'>YES<span style='color: black;'> if atypical or one-off subjective measure. <span style='color: red;'> Name the unvalidated measure in the notes.


Value:	Yes No Unsure No Data Not Applicable Other (please specify):
Notes:

13. ROBINS-I 1.6. Did the authors control for any post-intervention variables that could have been affected by the intervention?

Controlling for post-intervention (or after the start of the intervention) variables  is not appropriate. For example, compliance, number of sessions, intermediate outcomes (like pain during rehab).<br />
<span style='color: red;'>YES<span style='color: black;'> if any variables in model (other than intervention) were measured after the start of the intervention.<span style='color: purple;'> We might reject these studies.<br />
<span style='color: blue;'>NO<span style='color: black;'> if all variables measured pre-intervention (assume this is the case if not fully explicit).

14. ROBINS-I Risk of bias judgement for BIAS DUE TO CONFOUNDING

<span style='color: red;'>YES<span style='color: black;'> if answered Yes to any questions 1.1 to 1.6.<br />
<span style='color: blue;'>NO<span style='color: black;'> if answered No to all 1.1-1.6

15. ROBINS-I 2.1. Was selection of participants into the study (or into the analysis) based on participant characteristics observed after the start of intervention?

This domain is concerned only with SELECTION into the study based on participant characteristics observed after the start of intervention. Selection based on characteristics observed before the start of intervention can be addressed by controlling for imbalances between experimental intervention and comparator groups in baseline characteristics that are prognostic for the outcome (baseline confounding).<br />
<span style='color: blue;'>NO (low RoB)<span style='color: black;'> for RCT or for NRCS where eligibility criteria (including exclusion reasons) were based on (for example) receiving surgery or other criteria where those in either treatment group were enrolled based on criteria unrelated to their (rehab) treatment. If NO, skip questions 2.2 and 2.3.<br />
<span style='color: red;'>YES (high RoB)<span style='color: black;'> for NRCS where eligibility criteria were based, at least in part, on factors related to the choice of intervention.

16. ROBINS-I 2.2. If YES to 2.1: Were the post-intervention variables that influenced selection likely to be associated with intervention?

Selection bias occurs when selection is related to an effect of either intervention or a cause of intervention and an effect of either the outcome or a cause of the outcome. Therefore, the result is at risk of selection bias if selection into the study is related to both the intervention and the outcome.<br />
<span style='color: red;'>YES<span style='color: black;'> if an eligibility criterion is/may be related choice of intervention.<br />
<span style='color: blue;'>NO<span style='color: black;'> otherwise.

17. ROBINS-I 2.3 If YES to 2.2: Were the post-intervention variables that influenced selection likely to be influenced by the outcome or a cause of the outcome?

Selection bias occurs when selection is related to an effect of either intervention or a cause of intervention and an effect of either the outcome or a cause of the outcome. Therefore, the result is at risk of selection bias if selection into the study is related to both the intervention and the outcome.<br />
<span style='color: red;'>YES<span style='color: black;'> if an eligibility criterion is/may be related to both choice of intervention (Question 2.2)  and to an outcome of interest.<br />
<span style='color: blue;'>NO<span style='color: black;'> otherwise.

18. ROBINS-I 2.5. If YES to 2.2 and 2.3: Were adjustment techniques not used that are likely to correct for the presence of selection biases?

It is in principle possible to correct for selection biases, for example by using inverse probability weights to create a pseudo-population in which the selection bias has been removed, or by modeling the distributions of the missing participants or follow up times and outcome events and including them using missing data methodology. Propensity score analyses etc. would need to specifically account for these issues.<br />
However such methods are rarely used and the answer to this question will usually be <br /><span style='color: red;'>YES<span style='color: black;'>, no appropriate adjustment made. 

19. ROBINS-I - Risk of bias judgement for BIAS IN SELECTION OF PARTICIPANTS INTO THE STUDY

<span style='color: red;'>YES<span style='color: black;'> if answered Yes to any questions 2.1 to 2.3 and 2.6.<br />
<span style='color: blue;'>NO<span style='color: black;'> if answered No to all 2.1-2.6

20. NHLBI - POPULATION NOT PRESPECIFIED OR CLEAR

Were eligibility/selection criteria for the study population NOT prespecified and clearly described? Question reversed to maintain Yes/No meaning across questions.<br /><span style='color: blue;'>NO (good quality)<span style='color: black;'> if prespecified and clear (you could reasonably determine whether a patient in front of you would have been enrolled). By "prespecified" we mean that there were clear participant eligibility, whether prospective or retrospective design. <br /><span style='color: red;'>YES (poor quality)<span style='color: black;'> if not clearly prespecified or described. Explain in Notes.

21. NHLBI - INTERVENTION NOT CLEAR OR CONSISTENT

Was the intervention NOT clearly described and delivered consistently across the study population? Question reversed to maintain Yes/No meaning across questions.<br /><span style='color: blue;'>NO (good quality)<span style='color: black;'> if clear and consistent. Based on article, you are reasonably confident a therapist could reproduce the intervention AND all participants received the same intervention (in regards to the salient features of the intervention). <br /><span style='color: red;'>YES (poor quality)<span style='color: black;'> if not clear or consistently delivered. <br /><span style='color: purple;'>IF NOT CLEAR AND CONSISTENT, WILL LIKELY REJECT.

22. NHLBI - OUTCOMES NOT PRESPECIFIED, CLEAR, VALID

Were the outcome measures NOT prespecified, clearly defined, valid, reliable, and assessed consistently across all study participants? Question reversed to maintain Yes/No meaning across questions.<br /><span style='color: blue;'>No (good quality)<span style='color: black;'> if *all outcomes (of interest)* are clear and valid. Scores, scales, tools, etc. do not need to be formally validated, as long as the outcome measure is reasonable and appropriate. <br /><span style='color: red;'>YES (poor quality)<span style='color: black;'> if *all outcomes (of interest)* are problematic. <span style='color: purple;'>Explain in Notes. <br /><span style='color: brown;'>OTHER.<span style='color: black;'> If only some outcomes are high risk of bias. <span style='color: purple;'>Explain in Notes.

23. ROBINS-I 1.3. Were intervention discontinuations likely to be related to factors that are prognostic for the outcome?

... or related to the choice of intervention?<br />
Usually <span style='color: red;'>YES<span style='color: black;'> unless there is documentation that dropouts (or switches) were unrelated (eg, moved out of town)
