  1. T1: baseline, T2: 4 months from T1, T3: 7 months from T1. aThe lower score, the better sleep quality. bThe higher score, the more sleep disturbance
  2. $P-values were derived using mixed-effects linear regression modeling for continuous variables (sleep quality, sleep disturbance, weight, weight change from T1, and % weight change from T1) and using mixed-effects logistic regression for categorical variables (sleep duration and having ≥5% weight loss from T1). We did not present coefficient or odds ratio estimates from the regression models since the descriptive statistics (Mean ± SD and %) in the table are more straightforward to illustrate the extent of change across time
