Intra-rater reliability Clause Samples

Intra-rater reliability. Experienced users reported consistent values when using Methods 1 and 2. Intra-rater reliability values (PCC (95% CI)) were good to excellent for all measures: 0.79 (0.75, 0.82) for maximum EGJ diameter, 0.72 (0.66, 0.76) for distensive pressure, 0.74 (0.69, 0.78) for EGJ-DI, and 0.85 (0.82, 0.88) for distal esophageal body diameter (Figure 3).
