MB and rhabdomyolysis: Admission myoglobin performed significantly better than admission CK to predict severe rhabdomyolysis either with a maximum myoglobin exceeding 5000 μg/L (AUC–ROC 0.94 95% CI (0.91–0.97) and 0.88 95% CI (0.84–0.91), respectively, p < 0.001) or a maximum CK exceeding 5000 U/L (AUC–ROC 0.91 95% CI (0.88–0.94) and 0.88 95% CI (0.85–0.91), p = 0.013).
