Variables will be assessed for normality and log-transformed if appropriate. Baseline comparisons will be performed using Fisher’s exact tests and reported as n (%). Continuous normally distributed variables will be compared using Student t-tests and reported as means (standard deviation), while non-normally distributed data will be compared using Wilcoxon rank-sum tests and reported as medians [interquartile range].
