CRP and hyperhomocysteinemia: receiver operating characteristic (ROC) curve and precision‐recall (PR) curve analyses were performed, as shown in Figure 4A–C, both ROC (p < 0.001) (Figure 4A) and PR curves (p < 0.001) (Figure 4B) indicated that hyperhomocysteinemia had good performance in predicting the severity of coronary lesions, whose area under the curve (AUC) (0.669) was larger than other risk factors, including high Lp(a) levels (0.636), high hs‐CRP levels (0.582), older age (0.553), smoking (0.551), high BMI value (0.540) and large body weight (0.485).
