  • Note.—Differences in ages were compared by using ANOVA (at P < .05) with an a posteriori Tukey test (at P < .01). Other variables were assessed by using the Kruskal-Wallis test (at P < .05) with an a posteriori Mann-Whitney U test (at P < .01) to identify between-group differences. NS = not significant. Data in parentheses are total number of patients in each group. The score is the SD of the measurement.
