Intensity of renal replacement therapy in acute kidney injury: perspective from within the Acute Renal Failure Trial Network Study

Table 2 Pre-randomization RRT and 60-day all-cause mortality

	Intensive management strategy (n = 563)	Less-intensive management strategy (n = 561)	Odds ratio (95% CI)^a (between management strategies)
Without pre-randomization RRT	113/205 (55.1)	106/194 (54.6)	1.15 (0.85 to 1.53), P = 0.36
With pre-randomization RRT	189/358 (52.8)	182/366 (49.7)	1.00 (0.66 to 1.51), P >0.99
Odds ratio (95% CI)^a (within management strategy)	0.90 (0.62 to 1.30), P = 0.58	1.04 (0.71 to 7.50), P = 0.85

Data presented as number died/number at risk (%) or odds ratio (95% confidence interval (CI)). RRT, renal replacement therapy. ^aOdds ratio calculated by conditional logistic regression modeling adjusted for randomization strata.
