^*Adjusted for age, sex, alcohol intake, physical activity, weight, height, waist circumference, and calf muscle area.

^†Adjusted for variables included in Model 1 plus additional adjustment for Mini-Mental State Examination score, hypertension, diabetes mellitus, coronary heart disease, stroke, and peripheral artery disease.

^‡Adjusted for variables included in Model 2 plus additional adjustment for homeostasis model assessment and testosterone.

^§Adjusted for variables included in Model 3 plus additional adjustment for low-density lipoprotein cholesterol (LDL-C), oxidized LDL-C, and inflammation score.

^‖β is the difference in mean adjusted value for intermediate and highest HDL-C tertiles compared with the lowest.
