Effects of the combination of metformin and exercise on glycated hemoglobin, functional capacity, lipid profile, quality of life, and body weight
Bibliographic record
Abstract
Objective To evaluate the impact of the combination of metformin and exercise on changes in glycated hemoglobin (HbA 1c ), functional capacity, the lipid profile, quality of life, and weight. Methods Data from a 12-week cardiovascular rehabilitation program (2014–2016) were retrospectively evaluated. Metformin exposure was determined through recorded prescriptions, and average minutes of exercise per week were computed from exercise logs. The primary outcomes were changes in HbA 1c and functional capacity (6-minute walk test [6MWT]) over 12 weeks. The secondary outcomes were changes in the lipid profile, quality of life, and weight. Directed acyclic graphs were used to identify potential confounders, accounted for with multiple linear regression. Results The cohort comprised 403 patients (85 metformin users, 318 non-users). The average amount of exercise was 102.7±48.7 minutes/week among metformin users and 107.7±58.1 minutes/week among non-users. Although changes in HbA 1c were similar for both groups, the coefficient for the metformin–exercise interaction indicated significantly greater improvements in the 6MWT among metformin users. There were no between-group differences in any secondary outcomes. Conclusions The combination of metformin and exercise led to greater gains in functional capacity than exercise alone. This combination did not appear to influence the effects of either treatment on other outcomes.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
