OutcomeUnadjusted intervention scores Mean (SD; n)Unadjusted control scores Mean (SD; n)Adjusted difference(95% CI)*p ValueEffect size†
*Values adjusted for baseline outcome values and all minimisation variables as covariates (general health, main condition, gender, age, ethnicity and accommodation status).
†Effect size based on adjusted difference in means divided by the pooled standard deviation. Positive effect size represents favourable outcome for intervention.
‡Low scores indicate favourable outcome.
