Longitudinal Changes of Serum Creatine Kinase and Acute Kidney Injury among Patients with Severe COVID-19

Figure 2

Longitudinal trajectory of serum CK measurements relative to the time of hospital-acquired AKI evolution or last censored observation. Red, blue, orange, and black represent means of log serum CK concentrations (a) or CK concentrations in IU/L (b) for subjects with persistent AKI, rapid reversal AKI, and recovery AKI and without AKI, respectively; 95% confidence intervals are represented in shaded areas.
