  1. aThe values in the table are the predicted values derived from the Poisson regression model (primary outcome) or the logistic regression model (secondary outcomes) and their 95% confidence interval calculated with GEE methods.
  2. bP-value pertaining to a test of difference between Early ComRem and Late ComRem (Baseline period) or a test of difference between Early ComRem and Late ComRem beyond the difference found in the baseline period (the three follow-up periods).
