Figure 3From: The effect of continuous versus intermittent renal replacement therapy on the outcome of critically ill patients with acute renal failure (CONVINT): a prospective randomized controlled trialKaplan-Meier survival estimates for the subpopulation of patients with high vasopressor need (overall sample; high vasopressor use defined as >0.3 μg/kg/min at any point in time during the study interval) in the IHD (full line, n = 47) versus CVVH (dotted line, n = 40) groups are illustrated. Mantel-Haenszel log-rank P value, hazard ratio (HR), including 95% CI and χ2 is given.Back to article page
