Figure 6From: A randomized clinical trial of ascorbic acid in open abdominal aortic aneurysm repairEBC pH decreased in the placebo group from 7.38(0.04) to 7.32(0.08) (p = 0.008) after open AAA repair. In the ascorbic acid group the EBC pH fell from 7.40(0.05) to 7.29(0.06) (p = 0.002) post-operatively. The pre- and post-operative levels were similar between groups (Table 2).Back to article page
