Study Risk of Bias

1. Design
2. Clarity: Discrepancies
Was the article free of discrepancies (eg, between text and tables)? Add note if No (High concern)
3. Clarity: Population
Were patient eligibility criteria sufficiently clear? Add note if No (High concern).
4. Clarity: Intervention/Comparator
Were the ADP (and comparator) sufficiently clear? Add note if No (High concern)
5. Clarity: Outcomes
Were outcomes adequately defined without problem? Add note if No (High concern). Not every outcome requires an explicit definition (e.g., duration of ED stay).
6. Clarity: Setting
Was the setting sufficiently clearly defined? (Eg, Do we know the hospital (and ED) type?) Add note if No (High concern).
7. Missing data
Were there missing results data for ANY patients for outcomes that occurred in ED or hospital? Were there missing results data for >20% of patients (or imbalance between study groups) for outcomes that occurred after ED/hospital discharge? Add Note if Yes
8. Outcome ascertainment
9. RCT: Randomization & Allocation Concealment
Was there inadequate randomization method or allocation concealment? Whether randomization was done at the level of the ED or the patient, answer No, unless there's an obvious flaw. If Yes, add note.
10. Observational: Cohort representativeness
Eligible patients having ADP were all selected or a random selection was selected. No concerns about biased selection of ADP patients. Add note if No (high RoB)
11. NRCI: Comparator representativeness
Comparator group (or ED) was sufficiently similar (and selected patients were all included or a random sample were included). Add note if No (high RoB)
12. NRCI: Adjustment for confounders
