Table 1. Baseline demographic, anthropometric, and clinical characteristics.
Continuous variables were compared using the independent-samples (Welch) t-test; categorical variables were compared using the chi-square (χ²) test with 1 degree of freedom. Degrees of freedom (df) ranged from 63 to 66 for Welch-adjusted t-tests.
