The enter method was applied to this model, and adjusted analysis adjusted for age, BMI, waist circumstance, hip circumstance, calf circumference, TC, TG, HDL-C, LDL-C, HbA1c and HOMA-IR. All models included the same variables and categorizations/groupings, for visual presentation only significant variable categories are presented.
Β, regression coefficient; SE, standard error; 25(OH)D, 25-hydroxyvitamin D; HGS, handgrip strength; SMI, skeletal muscle index.
