Admission myoglobin performed better than CK for prediction of AKI any stage, (AUC–ROC 0.74 95% CI 0.68–0.79 and 0.63 95% CI 0.57–0.69, respectively, p < 0.001) as well as for prediction of AKI KDIGO 2 or 3 (AUC–ROC 0.79 95% CI 0.74–0.84 and 0.74 95% CI 0.69–0.79, respectively, p = 0.002) (Fig. 2). The gene discussed is MB; the disease is acute kidney injury.
