NCT06040723

Brief Summary

The Hill classification, also known as the Hill grade, is a system used to classify the severity of gastroesophageal valve incompetence, specifically related to gastroesophageal reflux disease (GERD) and hiatal hernia. This study aims to compare the ability of physicians versus an AI model to asses the Hill grade during gastroscopy.

Outcome Measures

Primary Outcomes (1)

  • Accuracy of assessments for the Hill classification for physicians and AI method.

    Binary assessment of physician vs AI correct and erroneous predictions.

    Through study completion, an average of 5 months

Secondary Outcomes (3)

  • Accuracy of assessments for each Hill grade for physicians and AI method.

    Through study completion, an average of 5 months

  • Precision and recall of the assessments for each Hill from endoscopists and AI method.

    Through study completion, an average of 5 months

  • Distance for label assessment from gold standard label.

    Through study completion, an average of 5 months

Study Arms (1)
