TASK: Your task is to answer biomedical questions using the given abstract. Only output yes, no, or maybe as answer.
INPUT: ['Graft-versus-host disease (GvHD) of the gastrointestinal tract is a major cause of morbidity and mortality after allogeneic bone marrow transplantation (BMT). Whether endoscopic findings predict the histologic diagnosis of GvHD in the gastrointestinal tract remains controversial. We performed a study to determine the diagnostic accuracy of macroscopic endoscopy findings in the diagnosis of acute and chronic histologically proven gastrointestinal GvHD (GI-GvHD).', 'Endoscopic images from the intestinal mucosa of post-BMT patients were blindly graded as positive or negative for GI-GvHD and compared with corresponding histological findings, which were used as the gold standard.', '44 BMT patients were referred for 96 endoscopic evaluations. Using 162 endoscopy-biopsy pairs, a positive association between endoscopic grading and histologic grading of GI-GvHD (odds ratio [OR] = 11.97, 95% CI 3.86, 37.16) was observed. Endoscopic diagnosis correctly predicted histologic diagnosis in both acute and chronic GI-GvHD (OR = 9.3 vs. 23.1, P = 0.31).'] Do endoscopic findings predict the histologic diagnosis in gastrointestinal graft-versus-host disease?
