Figure 2. A CI-AKI prediction nomogram integrated the predictors selected by Lasso, including sex, DM, LDH, Hs-CRP, years since drinking, CKD, stage of CKD, stroke, acute MI, and admission SBP.

The nomogram had excellent discriminative power with a C-statistic of 0.718 (95%CI: 0.637-0.800, p = 7.23 × 10-5) and was well calibrated with Hosmer-Lemeshow χ² statistic of 5.829 (p = 0.120).
