Table 2

Prevalence of GI symptoms and IAH during the ICU period and respective outcome of the patients. Differences between the groups (P value) were found using one-way ANOVA for continuous, and Kruskal-Wallis test for categorical variables.

	Number of pt (%)	ICU days (SD)	Mortality, pt (%)
Total	398 (100.0)	7.6 (9.1)	52 (13.1)
No GI symptom, no IAH	68 (17.1)	2.4 (1.6)	3 (4.4)
GI symptom(s) present, no IAH	178 (44.7)	5.4 (4.9)	18 (10.1)
IAH present, no GI symptom(s)	10 (2.5)	4.1 (1.9)	0 (0.0)
Both IAH and GI symptoms present	142 (35.7)	12.9 (12.3)	31 (21.8)
