Correlation of serum miRNA-23a and miRNA-23b expression with BMI in normal women (a and b), normal women at different stages of the menstrual cycle (c–k), and PCOS patients (l and m). The scatter plots with “r” and “p” values given are the ones that had significant correlation coefficients (p < 0.05)
