Value of renal angina index to predict AKI and mortality.

Renal Angina Index ≤8, n (%)	38 (37.2%)
AKI by Day 3, n (%)	33 (32.3%)
Sensitivity to predict Day 3 AKI, % (95% CI)	81.8 (67–91.9)
Specificity to predict Day 3 AKI, % (95% CI)	69.6 (62.5–74.4)
PPV to predict Day 3 AKI, % (95% CI)	56.3 (46.1–63.2)
NPV to predict Day 3 AKI, % (95% CI)	88.9 (79.8–95.0)
AUC for any RAI, % (95% CI)	0.73 (0.61–0.82)
AUC, RAI as change CrCl, % (95% CI)	0.62 (0.57–72)
AUC, RAI as Fluid overload, % (95% CI)	0.78 (0.59–0.88)
AUC, PRISM, % (95% CI)	0.66 (0.61–0.73)

RAI, Renal Angina Index; PPV, Positive Predictive Value; NPV, Negative Predictive Value; AUC, Area Under Curve; PRISM, Pediatric Risk of Mortality Score.
