Figure 3 Rates of renal failure shown by multiple definitions of the end point stratified over the cutpoint of 150 ml/h of urine flow induced by a forced diuresis, n = 98. = Low UFR (150 ml/h); = High UFR (>150 ml/h). p < 0.05. 1 indicates >25% rise in serum creatinine; 2 indicates >50% rise in serum creatinine; 3 indicates >100% rise in serum creatinine; 4 indicates >1.0 mg/dl rise in serum creatinine; 5 indicates a peak creatinine of >5.0 mg/dl at 48 h or dialysis. UFR = urine flow rate.
