| Risk of bias | ||
| Bias | Authors' judgement | Support for judgement |
| Random sequence generation (selection bias) | Unclear risk |
Quote from paper: "Four of the eight Residential Aged Care Facilities were selected at random.." Comment: method used not described |
| Allocation concealment (selection bias) | Unclear risk | Comment: not described |
| Blinding of participants and personnel (performance bias) All outcomes | Unclear risk | Comment: not described |
| Blinding of outcome assessment (detection bias) All outcomes | Unclear risk | Comment: not described |
| Incomplete outcome data (attrition bias) All outcomes | Unclear risk | Comment: insufficient reporting of attrition data |
| Selective reporting (reporting bias) | Low risk | Comment: reported all outcomes |
| Other bias | High risk |
Comment: baseline characteristics reported for whole group rather than for intervention and control separately Assessment of risk of bias in cluster‐randomised trials (1) Recruitment bias: unclear (2) Baseline imbalance: number of diagnoses (3) Loss of clusters: unclear (4) Incorrect analysis: yes (5) Comparability with individually randomised trials/different types of clusters: unclear |
