Figure 3From: Effect of mechanical ventilation on intra-abdominal pressure in critically ill patients without other risk factors for abdominal hypertension: an observational multicenter epidemiological study IAP in the ventilated and non-ventilated patients according to the age groups. Two independent sample t tests: p = 0.0001 (asterisk), p = 0.035 (double asterisk), and p = 0.001 (hash sign). MV, mechanical ventilation; IAP, intra-abdominal pressure; NS, no significance.Back to article page
