Defining hyperandrogenaemia according to the free androgen index in <scp>C</scp>hinese women: a cross‐sectional study

Abstract

A reference range of 0·7-6·4 FAI was indicated by the 5th and 95th percentiles among the reference group, which excluded the subjects with factors known to affect androgen levels; 6·1 was identified by the K-means cluster analysis as the cut-off value of the FAI for the general population. Hyperandrogenic women present with higher risks for metabolic disorders.
