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.
