Abstract
PURPOSE: The impact of comprehensive cardiac rehabilitation (CCR) in Latin America is not well known. Herein, the pre-specified tertiary outcomes of a cardiac rehabilitation (CR) trial are reported: disease-related knowledge, depressive symptoms, and heart-health behaviors (exercise, diet, and smoking). METHODS: This was a single-blinded, single-center (Brazil) randomized trial with three parallel arms: CCR (exercise + education) versus exercise-only CR versus wait-list control. Eligible patients were randomized in blocks of four with 1:1:1 concealed allocation. The CR program was 6 mo long. Participants randomized to exercise-only CR received 36 exercise classes; the CCR group also received 24 educational sessions, including a workbook. All outcomes were assessed at pre-test and 6-mo later (blinded). Analysis of covariance was performed by intention-to-treat (ITT) and per-protocol (PP). RESULTS: A total of 115 (89%) patients were randomized; 93 (81%) were retained. There were significant improvements in knowledge with CCR (ITT [51.2 ± 11.9 pre and 60.8 ± 13.2 post] and PP; P < .01), with significantly greater knowledge with CCR versus control (ITT mean difference [MD] = 9.5, 95% CI, 2.3-16.8) and CCR vs exercise-only CR at post-test (ITT MD = 6.8, 95% CI, 0.3-14.0). There were also significant improvements in self-reported exercise with CCR (ITT [13.7 ± 15.8 pre and 32.1 ± 2 5.7 post] and PP; P < .001), with significantly greater exercise with CCR versus control at post-test (ITT MD = 7.6, 95% CI, 3.8-11.4). Also, there were significant improvements in diet with CCR (PP: 3.4 ± 7.5 pre and 8.0 ± 7.0 post; P < .05). CONCLUSIONS: In this first-ever randomized trial of CR for coronary artery disease in Latin America, the benefits of CCR have been supported.

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 it
