Figure 1. Mendelian Randomization Associations of Genetic Predisposition to Type 2 Diabetes Mellitus and HbA1c Levels Among Diabetic and Nondiabetic Individuals.

(A) Type 2 diabetes. (B) HbA1c levels. Results derived from random-effects inverse-variance weighted analyses. Full circles correspond to statistically significant association estimates at a false discovery rate–adjusted p value < 0.05. CI = confidence interval; OR = odds ratio.
