Figure 2

The Kaplan-Meier curves categorized by the quartiles of baseline serum cystatin C levels. (a) In overall COVID-19 patients, serum cystatin C on admission was grouped into the levels of <0.90 mg/L (Q1), 0.90-1.08 mg/L (Q2), 1.08-1.36 mg/L (Q3), and ≥1.36 mg/L (Q4). (b) In COVID-19 patients without chronic kidney disease, serum cystatin C on admission was grouped into the levels of <0.89 mg/L (Q1), 0.89-1.06 mg/L (Q2), 1.06-1.31 mg/L (Q3), and ≥1.31 mg/L (Q4).
