Figure 1 (A) Plot of EGA-measured volume output (VO) against GA-measured VO with least-squares regression analysis. (B) Bland–Altman plot assessing agreement between EGA and GA VO with least-squares regression analysis. The mean difference (horizontal solid line) is plotted along with the 95% limits of agreement (dashed lines).

Figure 2 (A) Plot of EGA-measured AC against GA-measured AC with least-squares regression analysis. (B) Bland–Altman plot assessing agreement between EGA and GA AC with least-squares regression analysis.

Figure 4 Endoscopic images of a (A) submucosal hematoma secondary to trauma on insertion/placement of a (B) nasogastric tube that healed spontaneously after 2 weeks. (A) Submucosal hematoma confirmed during subsequent EGA. (B) Healed submucosal hematoma after 2 weeks.
