Fig. 3: Pairwise contrasts of pre-treatment percentage values between treatment arms (Arithmetic mean and their 95% confidence intervals).

Sample sizes used for each group were: PLA (n = 30), LEV-3 (n = 33), and LEV-5 (n = 28), except at Day 7, where the available sample sizes were PLA (n = 24), LEV-3 (n = 26), and LEV-5 (n = 18).
