- 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.
