APACHE II, Acute Physiology and Chronic Health Evaluation score; CI, confidence interval; RCC, respiratory care center; SE, standard error. *Variables with statistical significance (P < 0.05) in the univariate analyses (Tables 1, 2, and 3) were included in the multivariate logistic regression models. Backward variable selection was performed, and the criteria of P values for entry and stay were set at 0.05 and 0.10, respectively.
