¹13 had missing data.

²The other diagnostic yield included polyps (n = 8), gastritis (n = 6), strictures (n = 5), mass (n = 5), abnormal mucosa (n = 5), submucosal lesion (n = 4), diverticulum (n = 3), varices (n = 2), inflammation (n = 1), and miscellaneous (n = 9).

Therapeutic yield includes all therapeutic interventions excluding tissue sampling and polypectomy. Complications (n = 2) included minor oropharyngeal hemorrhage (n = 1), and minor esophageal trauma (n = 1).
