While there was a statistically significant and positive relationship between ovarian volume change and BMI values in the control group (p = 0.031), this relationship was not observed in the MDD group (p = 0.261), and while there was a statistically significant and positive relationship between FSH change and menstrual length in the MDD group (p = 0.019), this relationship was not found in the control group (p = 0.286; Table 3).
