IGFBP7 and Hypertension: The univariate analysis indicated that patients with AKI were older (hazard ratio, HR = 0.94, 95% CI: 0.90–0.99; p = 0.034); had a higher frequency of hypertension (HR = 6.02, 95% CI: 1.42–25.40; p = 0.014); had levels of [TIMP-2] × [IGFBP7] ≥ 0.2 (ng/mL)2/1000 (HR = 5.11, 95% CI: 1.20–21.67; p = 0.027); and NGAL ≥ 45 ng/mL (HR = 4.00, 95% CI: 1.15–13.81; p = 0.028).
