Figure 1: Receiver operator characteristic curves for diagnostic accuracy of RAI score in discriminating patients with severe AKI on days 3 and 7. (a) RAI had an AUC of 0.82 (95% CI: 0.73–0.90) in discriminating patients with severe AKI on day 3. Compared to RAI threshold of 12 or 20, RAI score ≥8 had lower Youden index (0.55 vs. 0.37), similar sensitivity (79.3% vs. 82.7%), and lower specificity [75.8% vs. 54.3%; Supplementary Table 1]. (b) AUC of RAI for severe AKI on day 7 was 0.73 (95% CI: 0.62–0.84). Compared to RAI threshold of 12 or 20, RAI score ≥8 had lower Youden index (0.41 vs. 0.34), similar sensitivity (68.4% vs. 73.7%), and lower specificity (75.8% vs. 52.3%). AUC: Area under the curve, CI: Confidence interval, RAI: Renal Angina Index, AKI: Acute kidney injury
