  1. Odds ratios (ORs), 95% confidence intervals (CIs), and p-values are adjusted for age, sex, and each baseline SF-36 subscale score. Centre for Epidemiologic Studies Depression Scale (CES-D) of 16 or higher was considered a depressive tendency, and the scores were treated as binary categorical data (CES-D ≥ 16 as 1; CES-D < 16 as 0).
