Fig 2 Kaplan-Meier curves show primary and secondary patency of aortofemoral reconstructions. Journal of Vascular Surgery 2011 53, 414-420DOI: (10.1016/j.jvs.2010.09.007) Copyright © 2011 Society for Vascular Surgery Terms and Conditions

Fig 3 Learning curves are shown for (top) anastomosis time and (bottom) operative time. The crosses mark individual times. The circles are calculated cumulative averages, and the thin lines above and below the circles are standard deviations of the cumulative average. The thick line is the estimated learning curve, and R2 is the degree of accuracy of estimation.

Fig 4 Cumulative summation (CUSUM) analysis of conversion rates is shown. The two horizontal lines at approximately 1.5 and –1.5 are h1, h0 boundaries. Journal of Vascular Surgery 2011 53, 414-420DOI: (10.1016/j.jvs.2010.09.007) Copyright © 2011 Society for Vascular Surgery Terms and Conditions
