2.4. Statistics
All the semiautomatically derived global and segmental parameters were assigned to GA descriptively. The data were compared between the beginner and expert using a Bland-Altman plot (average between the endoGLS, ED, FS or SI of the beginner and expert against the difference between these two) to test the agreement between both operators. GraphPad Prism 10 for Mac (version 10.1.1, GraphPad Software Inc., La Jolla, CA, USA) and Microsoft 365 Excel for Mac (Version 16.8.1, Microsoft Corp., Redmond, WA, USA) were used.
