  1. Data are presented as mean (95% CI) at baseline, and least-squares mean (95% CI) at 1 h, 2 h, 3 h, and 4 h, respectively
  2. Analysis was conducted using a mixed model for repeated measures, adjusting for baseline values
  3. *p Value for time effect—trend over time in all arms
  4. †p Value for treatment × time interaction—evaluates if changes in one arm are different from the changes in the other arms
  5. ‡p Value for comparison between arms at each moment
