T t-Student test for independent samples,W Mann–Whitney test,Q Chi-Square test,M adjusted (Monte Carlo) Chi-square,F Fisher exact test. Continuous data expressed in mean ± standard deviation for data with normal distribution and median (P25; P75) for data without normal distribution. n is less than the total number of patients due to missing data.
