  1. Measurements are reported as mean and standard deviation (SD), while changes are reported as mean difference and 95% confidence interval (CI). *: significantly different from the responsive subgroup (p < 0.05); #: significantly changed compared to baseline. R: responsive patients; S: Stable patients; N: non-responsive patients; BMI: body mass index.
