Statistical analysis:
Statistical analysis was performed using IBM® SPSS Statistics (V.1). Descriptive statistics were computed for all study variables. Kolmogorov-Smirnov normality tests were performed. Continuous data was reported as mean ± standard deviation and analysed using unpaired, two-tailed T-tests. Categorical data was analysed using Fisher’s Exact Test. Receiver Operator Characteristics (ROC) graphs were plotted and analysed; area under the curve (AUC) was used to quantify the diagnostic performance of each parameter. AUC=1 indicated perfect distinction between FHA and PCOS, whilst AUC=0.5 indicated no different from random selection.  P< 0.05 was considered statistically significant.
