  1. *Estimated between-group difference.
  2. §Odds-ratio.
  3. #Estimated treatment ratio (i.e., the ratio [semaglutide:placebo] between the geometric mean ratios of the week 52 value to the baseline value). The ratio to baseline and the corresponding baseline value were log-transformed before analysis. The approximate relative changes were derived from estimated ratios by subtracting 1 and multiplying by 100. The geometric mean ratio of the week 52 value to the baseline value was 0.58 in the semaglutide group and 0.87 in the placebo group. The estimated treatment ratio is calculated as 0.58/0.87 = 0.67.
