Figure 1From: Four hour creatinine clearance is better than plasma creatinine for monitoring renal function in critically ill patientsComparison of percentage increase in plasma creatinine (pCr) with percentage decrease in creatinine clearance (CCl) from known baseline to entry into the ICU. Four quadrants are shown: (i) No AKI (ΔpCrNo-AKI and ΔCClNo-AKI), (ii) AKI by the clearance criterion only (ΔpCrNo-AKI and ΔCClAKI), (iii) AKI by the pCr criterion only (ΔpCrAKI and ΔCClNo-AKI) or (iv) AKI by both criteria (ΔpCrAKI and ΔCClAKI). AKI: acute kidney injury; No-AKI (CClNo-AKI): without AKI; ΔpCr: relative change in pCr from baseline; ΔCCl: relative change in CCl from Cockcroft-Gault (CG) baseline; AKI (pCrAKI): with AKI.Back to article page
