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

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

  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  
  1. 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.
