Correlational analysis and the performance of individual adipokines and their ratios in predicting aPCOS. a Correlation among aPCOS group. b Correlation among ovulatory control group. Hierarchical clustering by Spearman’s correlation was used to assess relationship between adipokines and their ratios with obesity indices. Blue-red coloration represents min (−) to max (+) correlation coefficient. c Receiver operating characteristic (ROC) curve was based on binary logistic regression and discriminant classification analysis for aPCOS and control groups. ^†Test direction is negative (smaller test results indicate presence of condition). A:L ratio adiponectin:leptin ratio, A:R ratio adiponectin:resistin ratio, L:R ratio leptin:resistin ratio
