| Random sequence generation (selection bias) |
Low risk |
Randomization was performed via adaptive randomization procedures. Adaptive randomization can ensure better balance between groups in small and moderate sized studies than strict randomization, by continually adjusting the probability of assignment to either group, depending on existing group assignment. |
| Allocation concealment (selection bias) |
Low risk |
The allocation algorithm was concealed from both the participants and the research staff. |
| Blinding of participants and personnel (performance bias) |
High risk |
Blinding of participants and personnel was not possible due to the nature of the intervention and study design. |
| Blinding of outcome assessment (detection bias) |
High risk |
Several aspects of the study prohibited blinding, including the nature of the administered questionnaires (detailed housing history and service use), location of participant interviews (some participants elected to be interviewed at their place of residence) |
| Incomplete outcome data (attrition bias) |
Low risk |
No evidence of incomplete outcome data provided |
| Selective reporting (reporting bias) |
Low risk |
No evidence of reporting outcomes selectively is provided |
| Other bias |
Low risk |
No other potential risk of biases |
