Figure 5From: Urinary cystatin C is diagnostic of acute kidney injury and sepsis, and predicts mortality in the intensive care unitHypothetical time course of uCysC for a patient with both sepsis and AKI. The effect of AKI (dashed line) and sepsis (dotted line) on uCysC are additive (solid line). The shorter time course of AKI compared with the ongoing elevation in uCysC with ongoing sepsis may explain why uCysC was predictive of AKI at some times (for example, time point A) but not others (for example, time point B).Back to article page
