Abstract

fetched live from OpenAlex

Summary This study examined the change in weight at 6 months of naltrexone/bupropion (NB), a combination pharmacological therapy for weight management, in real‐world practice in Canada. The study was conducted through an observational, retrospective, single‐arm chart review of adult patients who attended the Wharton Medical Clinic in Ontario, Canada, between 2018 and 2021. The patients had a body mass index ≥30 or ≥27 kg/m 2 with at least one weight‐related comorbidity. They were prescribed NB, titrated from 1 (8 mg/90 mg) to 4 tablets daily, along with lifestyle modification. Approximately 52% of 468 participants completed 6 months of treatment and 48.7% titrated to the maximum dose of 4 tablets daily. Participants were mainly female, with mean age of 49.5 years and BMI 38.4 kg/m 2 . After 6 months, participants lost a mean of 4.23 kg (95% confidence interval [CI] −4.99, −3.47) or 4.05% (CI −4.77, −3.34) of body weight, with 42.5% losing at least 5% of their body weight and 15.5% losing at least 10%. The most frequent adverse events were nausea (5.7%), constipation (5.7%), and headache (2.5%). Participants also experienced decreased appetite (14.7%), decreased cravings (13.9%), decreased hunger (9.4%) and felt full sooner (2.5%), which are changes likely to result in sustained healthy food choices and improved quality of life. The 6‐month NB treatment adjunct to lifestyle modification in a real‐world population resulted in clinically significant weight loss.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
