Table 4 shows results of multiple linear regression analysis between BMD and CAVI. CAVI is the dependent variable.
Model 1: crude model; model 2: adjusted for age, gender, BMI, smoking, history of CVD and history of DM; model 3: adjusted for age, gender, BMI, smoking, history of CVD, history of DM, SBP, HDL-C and blood UA.
B, unstandardised coefficients; BMD, bone mineral density;BMI, body mass index; CAVI, cardio-ankle vascular index; CVD, cardiovascular or cerebrovascular disease; FN FN BMD, femoral neck BMD;HDLC, high-density lipoprotein cholesterol; LS BMD, BMD in the lumbar spine; SBP, systolic blood pressure; TH BMD, total hip BMD; UA, uric acid; eGFR, estimated glomerular filtration rate.
