In addition, the ROC curve (figure 3) demonstrated that the AUCs of PNI and GNRI were significantly higher than that of CONUT score, and AUC of PNI, GNRI and CONUT score were larger than those of the components of these scores (ie, albumin, total cholesterol, total lymphocyte count and BMI) in patients with HF (n=691). This evidence concerns the gene ALB and hydrops fetalis.
