Fig 1 A, Cumulative sum (CUSUM) analysis of composite outcome of death or any major complication. The red and green lines represent 90% alert (red) and 90% reassurance (green) boundaries. ALM/CLA, Arc line measurement with centerline adjustment; CTs, constraining ties. P0 (acceptable failure rate) = 12.5%, P1 (unacceptable failure rate) = 20.0%, α (type I error rate) = β (type II error rate) = 10%. B, Adjusted CUSUM analysis of composite outcome of death or any major complication. Plot was constructed using the predicted probability of death or major complication from the model in Table V rather than the actual outcome.

Fig 2 Scatterplots of (A) procedure time, (B) fluoroscopy time, (C) contrast material administered, and (D) estimated blood loss as a function of case number. Data are presented for cases with two or more fenestrations for (A) and (B) and for the entire sample for (C) and (D). ALM/CLA, Arc line measurement with centerline adjustment; CTs, constraining ties. Journal of Vascular Surgery , DOI: ( /j.jvs ) Copyright © Terms and Conditions
