Table 3 Final multiple logistic regression model for RRT dependence at hospital discharge in survivors.

From: Fluid balance, intradialytic hypotension, and outcomes in critically ill patients undergoing renal replacement therapy: a cohort study

Variable Unadjusted OR P value Adjusted OR P value
(95% CI) (95% CI)
Mean daily fluid balance (per 1000 mL positive) 0.91 (0.74-1.12) 0.36 0.93 (0.75-1.16) 0.54
Intradialytic hypotension (per 10% increase in number of days) 1.01 (0.92-1.11) 0.86 1.02 (0.92-1.13) 0.69
Male sex 1.05 (0.58-1.91) 0.87 1.20 (0.62-2.31) 0.59
Congestive heart failure 2.60 (1.30-5.19) 0.007 3.13 (1.46-6.74) 0.003
Medical (versus surgical) diagnosis 1.84 (1.02-3.32) 0.04 1.75 (0.88-3.47) 0.11

  CRRT vs. IHD 0.52 (0.26-1.04) 0.06 0.72 (0.31-1.65) 0.43
  sLED vs. IHD 1.18 (0.51-2.75) 0.70 1.51 (0.60-3.83) 0.38
  1. The final model had 241 survivors and 61 patients with RRT dependence at hospital discharge; it did not demonstrate lack of goodness of fit (Hosmer-Lemeshow P = 0.69). CI, confidence interval; CRRT, continuous renal replacement therapy; IHD, intermittent hemodialysis; OR, odds ratio; RRT, renal replacement therapy; SLED, sustained low-efficiency dialysis; SOFA, sequential organ failure assessment score.
