Table 2.

Effect of aspirin on outcome of critically ill patients characterised in Table 1. Odds ratios for ICU mortality were calculated using data from our recently published study [33]. The model of stepwise logistic regression included age, gender, APACHE II score, and preexisting medication with aspirin as independent variables.

Variable	Odds ratio (95% CI)
Age	1.04 (1.03–1.06)
APACHE II score	1.16 (1.13–1.20)
Aspirin	0.20 (0.12–0.35)
