^aGroup effects based on mixed effects linear models with baseline as covariate, and with illness duration, time and treatment group, and their interactions as fixed effects. Degrees of freedom vary across analyses due to missing data.

^bEffect size calculated by dividing model-based estimates of mean differences at the end of the study by pooled within-group standard deviation of raw scores.

^cSum of single scores.
