Basal total cholesterol, triglycerides, low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and changes in these parameters in the diabetic patients after 1 year of atorvastatin or simvastatin treatment, stratified by the percentile changes in HDL-C (i.e. ΔHDL-C ≥ 3%, -3% < ΔHDL-C < -3%, and ΔHDL-C ≤-3%). P-value: trend analysis for percentage change. * p < 0.05 compared with baseline.
