Fig 2 Cumulative sum (CUSUM) plot for all repairs. Vertical dashed line indicates the introduction of the ruptured abdominal aortic aneurysm endovascular aneurysm repair (EVAR) protocol. After the introduction of the protocol, the lower CUSUM line crosses the “superior” line within 35 surgeries (P = .059).

Fig 3 Cumulative sum (CUSUM) plots for (A) endovascular aneurysm repair and (B) open repairs after the introduction of the EVAR protocol. Note the stable performance of open repairs, with a trend towards improvement in the performance of endovascular repairs.
