Fig. 7From: Application of double layered end-to-end anastomosis with continuous manual suture for completing digestive tract reconstruction in totally laparoscopic distal gastrectomyCUSUM analysis for operation time and anastomosis time. The operation sequence as horizontal axis and CUSUM value as vertical axis. The fitting model test was based on P value, P < 0.05 as the standard of curve fitting success. The goodness of fit is determined by coefficient R2, that is, the closer R2 is to 1. a CUSUM analysis for operation time. b CUSUM analysis for anastomosis timeBack to article page
