Figure 2: Comparison among the AUCs of MDA-LDL, MDA-LDL/LDL-C, MDA-LDL/HDL-C, and (MDA-LDL/LDL-C)/HDL-C for the presence of coronary artery stenosis. The AUCs (95% confidence interval) were as follows: MDA-LDL 0.675 (0.496–0.854), MDA-LDL/LDL-C 0.765 (0.602–0.927), MDA-LDL/HDL-C 0.752 (0.592–0.913), and (MDA-LDL/LDL-C)/HDL-C 0.799 (0.643–0.955). MDA-LDL: malondialdehyde-modified LDL; MDA-LDL/LDL-C: MDA-LDL-to-LDL cholesterol ratio; MDA-LDL-C/HDL-C: MDA-LDL-to-HDL cholesterol ratio; (MDA-LDL/LDL-C)/HDL-C: (MDA-LDL/LDL-C) to the HDL cholesterol ratio.
