A receiver operator characteristic curve for plasma cystatin C as an overall predictor of death in subjects with COPD exacerbation. Area under the receiver operator characteristic curve = 0.77 (95% CI 0.70–0.84).
- Fig. 2.
Cystatin C levels (mg/L) in survivor and non-survivor subjects with COPD exacerbation stratified by the comorbid presence of renal dysfunction (A) and congestive heart failure (B) at the time of admission. Boxes show first and third quartiles, center lines denote the median, and whiskers show the minimum and maximum. * P < .05.

Cystatin C levels (mg/L) in the survivor and non-survivor subjects with COPD exacerbation stratified by the levels of pH (A), PaO2 (B), and PaCO2 (C). Low pH is <7.35, and high pH is >7.35; low PaO2 is <60 mm Hg, and high PaO2 is ≥60 mm Hg; low PaCO2 is <50 mm Hg, and high PaCO2 is ≥50 mm Hg. Boxes show first and third quartiles, center lines denote the median, and whiskers show the minimum and maximum. * P < .05.
