DIAPH1 and polycystic ovary syndrome: FBG levels in women with PCOS were not significantly different between the DIAPH1-quantile subgroups (Figure 2(g)), but HOMA-β levels were significantly higher in PCOS women with lower DIAPH1 levels in the first (2.25-fold, P < 0.05 for Q1 vs. Q4) and second quantiles (2.28-fold, P < 0.05 for Q2 vs. Q4) compared to women with the highest DIAPH1 levels in the fourth quartile (Figure 2(h)).
