Figure 1From: Retrospective study of the effectiveness of Intra-Aortic Balloon Occlusion (IABO) for traumatic haemorrhagic shock Comparison of systolic blood pressure (SBP) of trauma patients who underwent intra-aortic balloon occlusion (IABO). A: Comparison of SBP before and after IABO in all cases (n = 14). B: Comparison of the change in SBP (∆SBP) between the survived group (n = 5) and non-survived group (n = 9). Values are reported as mean ± SE, analysed using a Wilcoxon signed rank test (A) or Mann-Whitney U test (B). *P < 0.05, **P < 0.01, ***P < 0.001.Back to article page
