The Geriatric Nutritional Risk Index Independently Predicts Mortality in Diabetic Foot Ulcers Patients Undergoing Amputations

Figure 2

Kaplan-Meier survival curves of the proportion of patients with mortality, according to (a) GNRI categories (low GNRI, <92; high GNRI, ≥92), (b) eGFR stratification (eGFR, ≥90; 60 ≤ eGFR < 90; 30 ≤ eGFR < 60; eGFR < 30), or (c) amputation categories (minor amputation; major amputation). The differences between groups in (a) and (b) were significant (log-rank test, all ). There was no significant difference in (c) between groups (log-rank test, ).
