Data are presented as median (interquartile range) or n / total n (percent). Data related to ultrasonographic features reflect the mean of recorded values from the right and left ovaries rounded to the nearest whole number.

Within rows, an asterisk denotes a significant difference between groups based on the Mann-Whitney U (for continuous variables) or Fisher’s Exact test (for categorical variables), p < 0.05.

Abbreviations: FNPO, follicle number per ovary; FNPS, follicle number per cross-section; OV, ovarian volume.
