Categorical variables (sex) are summarized with counts and (percentages), and tested with a χ² test. Continuous variables that are sufficiently normal are summarized with means ± SDs, and tested with t tests. Continuous variables that are highly skewed and heteroscedastic are summarized with medians and [quartiles], and tested with the Mann-Whitney U test.
