Variation of Risk Factors for Cause-Specific Reintubation: A Preliminary Study

Table 4

Propensity score analysis in the respiratory insufficiency group.

P/F ≤ 200	Logistic regression using propensity scores (adjusted for age, APACHE score, intubation duration, and RSBI)
	OR	95% CI	value
Reintubation group	4.004	0.776 to 20.664	0.098
Respiratory insufficiency group	7.811	1.345 to 45.367	0.022

APACHE, acute physiology and chronic health evaluation; CI, confidence interval; OR, odds ratio; P/F ratio, pressure of arterial oxygen to fractional inspired oxygen concentration ratio; RSBI, rapid shallow breathing index.
