For categorical variables, n (%) is presented.

For continuous variables, mean (SD)/median (min; max)/n is presented.

For comparison between groups, Fisher's exact test (lowest 1-sided p value multiplied by 2) was used for dichotomous variables and the Mann–Whitney U test was used for continuous variables.
