SHBG and type 2 diabetes mellitus: After adjusting for age, BMI, Townsend index and smoking status, the risk of T2DM increased in men with SHBG levels < 40 nmol/L; aIRR of incident T2DM increased across categories of decreasing SHBG concentrations as compared to the reference category (≥60 nmol/L) and the risk was more than 5‐fold higher in the group with SHBG < 20 nmol/L (aIRR 5.74, 95% CI 3.72‐8.87, Table 2 & Figure 1C,D).
