Effectiveness and Utilization of Cardiac Rehabilitation Among People With CKD
Bibliographic record
Abstract
INTRODUCTION: Cardiac rehabilitation (CR) is a proven therapy for reducing cardiovascular death and hospitalization. Whether CR participation is associated with improved outcomes in patients with chronic kidney disease (CKD) is unknown. METHODS: or kidney replacement therapy defined CKD. Predictors of CR use were estimated with multinomial logistic regression. The association between starting versus not starting and completion versus noncompletion of CR and clinical outcomes were estimated using multivariable Cox proportional hazards models. RESULTS: Of 23,215 patients referred to CR, 12,084 were eligible for inclusion. Participants with CKD (N = 1322) were older, had more comorbidity, lower exercise capacity on graded treadmill testing, and took longer to be referred and to start CR than those without CKD. CKD predicted not starting CR: odds ratio 0.73 (95% confidence interval [CI] 0.64-0.83). Over a median 1 year follow-up, there were 146 deaths, 40 (0.3%) from CKD and 106 (1.0%) not from CKD. Similar to those without CKD, the risk of death was lower in CR completers (hazard ratio [HR] 0.24 [95% CI 0.06-0.91) and starters (HR 0.56 [95% CI 0.29- 1.10]) with CKD. CONCLUSION: CR participation was associated with comparable benefits in people with moderate CKD as those without who survived to CR. Lower rates of CR attendance in this high-risk population suggest that strategies to increase CR utilization are needed.

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.
