Data were analyzed by unpaired t-tests. All values are expressed as mean ± standard deviation for continuous variables and as number of patients (percentage) for categorical variables. Continuous variables were analyzed by independent-sample t-tests; two-sided type I error of 0.05. Categorical variables were analyzed by χ2 tests. RCC, renal cell carcinoma; BMI, body mass index; WC, waist circumference; BBT, basal body temperature; SBP, systolic blood pressure; DBP, diastolic blood pressure; RHR, resting heart rate; FBG, fasting blood glucose; TG, triglyceride; TC, total cholesterol; LDL-C, low-density lipoprotein cholesterol; HDL-C, high-density lipoprotein cholesterol; Cr, creatinine; CCr, creatinine clearance rate.
