ESR imbalance ratios at all points on the first day of menstrual period in healthy volunteer group are given in column of Group A-1, while those on the third day after menstrual period are given in column of Group A-3. Corresponding values of dysmenorrhea group on those two days are given in column of Groups B-1 and B-3, respectively. values are from within-group comparisons of group A on two days using Kruskal-Wallis Test. values are from within-group comparisons of group B on two days using Kruskal-Wallis Test. values are from between-group comparisons of groups A and B on the first day of menstrual period using Kruskal-Wallis test. values are from between-group comparisons of groups A and B on the third day after menstrual period using Kruskal-Wallis test.
