Figure 5 . Analysis of the height of the LA roof as a predictor of GH.
A: ROC curve for predicting GH, regarding the height of the LA roof from the point where the LAPW and esophagus make contact. The cutoff value for the height of the LA roof was calculated as 6.1 mm (AUC: 0.90; sensitivity: 85.0%; specificity: 83.0%).
B: The prevalence of GH is shown according to the height of the LA roof, with the cutoff value calculated using the ROC curve. The frequency of GH occurrence was significantly higher in patients with a lower height of the LA roof.
AUC, area under the curve; GH, gastric hypomotility; LA, left atrial; LAPW, left atrial posterior wall; ROC, receiver-operating characteristic.
