†: Odds ratio, ‡: Confidence interval, *: Chronic obstructive pulmonary disease, ☸: Length of stay.

In the univariate logistic regression analysis, the variables of the multivariate analyses were excluded owing to P being >0.25.

Cox-Snell R square: 0.373, Hosmer–Lemeshow P: 0.7998, Confidence interval: 95%.
