Cox regression analysis of all-cause death separately by BMI or age. The HR (95% CI) of all-cause deaths according to the presence of diabetes and BMI are shown separately in those aged <65 years (A) and those ≥65 years (B). The analysis was adjusted for sex, current smoking status, systolic BP values, and pre-existing myocardial infarction, stroke, or cancer. The reference group was defined as nondiabetes with normal BMI. Statistical significance was defined as P < 0.05. *P < 0.05 vs. reference group, †P < 0.01 vs. reference group, and ‡P < 0.001 vs. reference group.
