Fig. 1From: Higher plasma cystatin C is associated with mortality after acute respiratory distress syndrome: findings from a Fluid and Catheter Treatment Trial (FACTT) substudyBox and whisker plots of the raw plasma cystatin C data in the full cohort and stratified by Kidney Disease: Improving Global Outcomes (KDIGO) acute kidney injury (AKI) status show that cystatin C is higher among those who died by 60 days compared to those who survived. This difference was statistically significant by Wilcoxon’s rank-sum testing in the full cohort and both strata of AKI status. The cystatin C quartile cutoffs were established in the full cohort and applied to the data stratified by AKI statusBack to article page
