Intra-Abdominal Hypertension and Gastrointestinal Symptoms in Mechanically Ventilated Patients

Table 1

Characteristics of the patients. The values for admission day are presented as mean (SD) if not stated otherwise. Differences between the groups (P value) were found using one-way ANOVA for continuous variables and Kruskal-Wallis test for categorical variables.
