Las Vegas, NV - October 27th, 2021: At the American College of Gastroenterology conference in Las Vegas, Dieta unveiled its AI validation study in partnership with the MAST Program of Cedars Sinai Medical Center. Dieta was honored to win the ACG Presidential Poster Award for this research, a prestigious award that is given to less than 5% of gastroenterology abstracts.
The purpose of this study was to validate Dieta’s stool image recognition technology as an accurate outcomes measurement tool in human GI clinical trials. As a sub-study or a larger human clinical trial, a group of 14 patients were randomly selected and 219 associated stool images captured from the Dieta mobile app in the clinical trial were assessed. 2 expert gastroenterology professors then manually annotated each image with 5 different stool characteristics. The range or scores for each variable was (1-7) for Bristol Score and 0-100 for each of consistency, edge fuzziness, fragmentation and volume. Dieta’s computer vision AI algorithms also scored the same set of images for comparison and validation. There was a strong agreement between the experts and AI for most of stool characteristics. The agreement with AI was not different from the agreement between the 2 experts (Dr. Mark Pimentel and Dr. Ali Rezaie).
A full academic medical paper will be published in a peer reviewed journal detailing this research in the months to come.
