Note. BMI, body mass index; PD, primary dysmenorrhea. Superscript numbers indicate the absence (a) or presence (b,c) of statistically significant differences. The Minitab®16 statistical program (Minitab Inc., State College, PA, USA) was used to perform the statistical analysis. The Shapiro–Wilk test was used to evaluate the normality assumption of the data and Levene’s test was used to assess the variance homogeneity assumption. Values are expressed as mean ± standard deviation. Parametric comparisons were made via t-test or z-test, and nonparametric comparisons were made via Mann–Whitney U test. was considered statistically significant.
