Note: CI = confidence interval, MA = monitoring alone, SCA = small change approach, SE = standard error.
*
Values are expected mean changes (with standard errors or 95% confidence intervals, as applicable) from mixed-effects models, adjusted for baseline measurements and sex with control-based multiple imputation of missing values.
