Comparison of mobilisation-observation-behaviour-intensity-dementia-2 (MOBID-2) pain scale total score between control and intervention (stepwise protocol for treatment of pain) groups using repeated measures analysis of covariance (ANCOVA)*
| Week | Mean (SD) MOBID-2 total | Effect of intervention on MOBID-2 total† | Intracluster correlation coefficient‡ | ||
|---|---|---|---|---|---|
| Control group | Intervention group | Estimate (95% CI) | P value | ||
| 0 | 3.7 (2.5), n=163 | 3.8 (2.7), n=164 | 0.094 | ||
| 2 | 3.5 (2.4), n=159 | 2.9 (2.5), n=152 | −0.7 (−0.4 to −1.1) | <0.001 | 0.070 |

*Baseline score as covariate and least squares weighted by number of patients within cluster; P value from multivariate test of intervention was <0.001, and cross effect between week and intervention was 0.009.
†Variable estimate by week of effect of intervention on MOBID-2 from estimated model.
‡Proportion of total variance between clusters, and measured within framework of ANCOVA.
