CUSUM curves associated with anastomotic leak, clinical anastomotic failure, and anastomotic failure. A–F simple CUSUM curve, B–G Bernoulli Cumulative Deviation Curves for simple CUSUM, C–H RA-CUSUM curves, D–I Bernoulli Cumulative Deviation Curves for RA-CUSUM, and E–J simple CUSUM curve using a reference mean from the literature. CumDevPosit cumulative sum of the positive deviations, CumDevNeg cumulative sum of the negative deviations, CumDevMean mean of the CumDevPos and CumDevNeg values
