In controls, glypican-4 levels showed a positive correlation with galanin levels as well as age, BMI and mFG scores, whereas DHEA-SO4 and free testosterone levels were negatively correlated (p < 0.025 according to the Bonferroni correction).Tables 2and3demonstrate the correlations of both galanin and glypican-4 levels with clinical, metabolic, hormonal and androgen excess parameters. Here, GPC4 is linked to hyperandrogenism.
