Statistical Analysis
REGRESSION
Analyses were conducted using Stata statistical software version 16 (StataCorp) from August to October 2022. We ran 3 main models—multivariable Tobit regression, propensity score matching (PSM), and IV analysis. Owing to regression to the mean when using within-person change scores, we used the 24-week follow-up HADS scores, with adjustment for baseline HADS score.
