Clinical and Epidemiological Characteristics of Rhabdomyolysis: A Retrospective Study

Table 6

The predictive value of CK, creatinine, and combined testing for RM-AKI.

Category	AUC (95% CI)	Cutoff	Sensitivity (%)	Specificity (%)	Youden (%)
CK	0.751 (0.635∼0.867)	12945.5	87.5	58.2	0.457
Creatinine	0.915 (0.834∼0.996)	112.50	93.8	80.0	0.738
Combined testing	0.949 (0.901∼0.997)	—	87.5	89.1	0.766

RM: rhabdomyolysis; AKI: acute kidney injury; CK: creatine kinase; AUC: area under the curve.
