A Kaplan-Meier curve was created using historical control data obtained from morbidly obese patients (BMI > 50) awaiting bariatric surgery. Subjects did not receive any diet intervention. Participants all received the same test for negative alliesthesia described in the methods section. Both groups showed a similar satiety kinetic for sweet stimulus (Log-rank chi-square = 0.045, df = 1, p = 0.8311, NS). The median time to achieve satiety in both groups were comparable (Initial session 25.5 min vs. 3 month 30 min). These results suggest the test is reproducible in a clinical setting for patients.
