Cluster-level analysis of weight management variables and lifestyle advice with imputed outcomes at baseline
| Control (n = 13) | Intervention (n = 12) | Mean difference | ||||
|---|---|---|---|---|---|---|
| Baseline (imputed) | Follow-up | Baseline (imputed) | Follow-up | Mean (95 % CI) | p value | |
| Weight management | 8.8 % (8.5 %) | 14.7 % (11.9 %) | 5.1 % (2.8 %) | 13.6 % (6.4 %) | 3.7 (−2.5, 9.9) | 0.23 |
| Referral to external weight loss services | 4.5 % (5.8 %) | 4.3 % (3.0 %) | 2.8 % (3.0 %) | 3.8 % (3.6 %) | 0.5 (−2.2, 3.1) | 0.73 |
| Internal weight management | 4.2 % (4.0 %) | 9.9 % (10.1 %) | 2.3 % (2.0 %) | 9.0 % (7.1 %) | 3.3 (−1.7, 8.3) | 0.18 |
| Lifestyle assessment | 0.0 % (0.0 %) | 23.4 % (8.2 %) | 0.9 % (2.1 %) | 24.3 % (5.8 %) | −0.2 (−6.9, 6.5) | 0.95 |
The outcomes here are continuous cluster-summary variables (percentage of patients with the outcome) as opposed to patient-level binary variables. xx.x% (xx.x%) = mean (SD). A mean difference >0 favours the intervention group
