Figure 1. Differences in the levels of bisphenols, OH-PAHs, parabens, and mPAEs in follicular fluid based on demographic characteristics. (A) Age; (B) BMI; (C) Basal_T; (D) Infertility form. The lower and upper limits of the box denote the 25th and 75th quartiles, respectively. The horizontal line within the box represents the median value. The length of the whiskers is 1.5 times the interquartile range. The rhombus symbol denotes the 99th percentile. The small rectangular boxes represent average values, and the star symbol indicates that there are significant differences between groups [Kruskal–Wallis H and Mann–Whitney U tests were used. ^*P < 0.05 (2-tailed)]. OH-PAHs: Hydroxyl polycyclic aromatic hydrocarbon; mPAEs: phthalate metabolites; BMI: body mass index; Basal_T: basal testosterone.
