The sex-specific association of all-cause mortality with MMA levels across diabetes status

The restricted cubic spline curve showed the adjusted hazard ratios in adults with (A) no diabetes, (B) prediabetes, and (C) diabetes for all-cause mortality based on the Cox regression model (unweighted). The model was fully adjusted for age, race/ethnicity, smoking, physical activity, BMI, hypertension, cancer, CVD, TC/HDL-C ratio, eGFR, HbA1c, and serum cobalamin. The solid line represented point estimates, and the dashed lines represented 95% CIs.
