Figures & data
Table 1. Baseline characteristics of participants according to AKI occurrence.
Figure 1. A multiple-variable adjusted restricted cubic spline method was used to depict the relationship between GNRI and the occurrence of AKI in patients with AHF. The shaded area represents the 95% CI. HR: hazard ratio; CI: confidence interval; GNRI: Geriatric Nutritional Risk Index.
Figure 2. ROC curves of GNRI, CONUT and PNI for predicting the occurrence of AKI in patients with AHF. GNRI: Geriatric Nutritional Risk Index; CONUT: Controlling Nutritional Status; PNI: Prognostic Nutritional Index.
Figure 3. Kaplan–Meier curve for the occurrence of AKI in patients with AHF. GNRI: Geriatric Nutritional Risk Index; Time: The number of days of ICU stay.
Table 2. Threshold analyses of GNRI on AKI occurrence using two-piecewise regression models.
Table 3. The relationship between the GNRI and AKI occurrence in a cox regression model.
Table 4. Subgroup analyses of association between GNRI on AKI occurrence in critically ill patients with AHF.
