  1. Data are means ± SD or median (interquartile ranges) for indicated number of patients in each group. P values for comparisons between groups are based on unpaired t test or Mann–Whitney Test (when the data are not normally distributed). Bold entries represent significant p values. The P < 0.05 is considered to be significant.
