Furthermore, the subgroup analysis revealed that the incidences of CKD were 0.6% (95% CI: 0.1 to 17.1) and 1.4% (95% CI: 0.7 to 2.0) when rhabdomyolysis was diagnosed based on serum CK and/or myoglobin levels and serum CK levels, respectively (Fig. 9). This evidence concerns the gene MB and chronic kidney disease.
