Figure 1 Endoscopic measurement technique of the GJ stoma diameter. A flexible calibrated measuring instrument is introduced through the upper endoscope working channel and placed in proximity to the GJ stoma. The endoscopist recorded its maximal diameter.

Figure 2 Scatter plot with best-fit linear regression line and 95% confidence intervals of the association between the GJ stoma diameter in millimeters and percentage of maximal weight lost after RYGB that was regained. The normal distribution of each of the continuous variables is also shown.
