- * Overall P = .03
- Binary logistic regression analysis with centers ranked according to their frequency of RRT treatment offered, with the center showing the lowest frequency of RRT taken as reference category. Center risk was controlled for individual treatment offered (conservative versus RRT) and individual disease severity (SHARF score).
- RR (95% CI), relative risk with 95% confidence interval; RRT, renal replacement therapy.
