What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Cardiac rehabilitation (CR) significantly improves outcomes for patients with cardiovascular disease, but delivering consistently personalized exercise prescriptions remains challenging due to resource limitations and practice variability. Artificial intelligence (AI), particularly large language models (LLMs), may support the generation of guideline-adherent baseline exercise programs. Objective: This study aimed to assess the adherence to guidelines, expert-evaluated safety, and clinical plausibility of AI-generated exercise prescriptions for cardiac rehabilitation across common cardiac conditions in simulated clinical scenarios. Methods: Exercise prescriptions generated by DeepSeek were evaluated using five purpose-designed simulated clinical profiles: recent myocardial infarction (<1 month), prior myocardial infarction (>1 month), atrial fibrillation, heart failure with reduced ejection fraction (EF 35%), and heart failure with preserved ejection fraction (EF 50%). For each profile, the model was prompted to generate a 30-day CR exercise program in accordance with FITT-VP principles (Frequency, Intensity, Time, Type, Volume, Progression), standard safety considerations, and current American Heart Association/European Society of Cardiology (AHA/ESC) guideline recommendations. Two experienced CR specialists independently evaluated the generated programs for adherence to guidelines, safety, and clinical plausibility. Results: The model successfully generated unique 30-day exercise programs for all five profiles, incorporating warm-up and cool-down phases, aerobic and resistance training components, intensity guidance using rating of perceived exertion and/or heart rate targets, and progressive adaptation over time. The programs demonstrated appropriate condition-specific modifications, such as lower-intensity exercise for recent myocardial infarction and heart failure with reduced ejection fraction, and avoidance of high-intensity exercise bursts in atrial fibrillation. Expert evaluation confirmed broad adherence to the FITT-VP principles and the major safety recommendations of the current AHA/ESC guidelines. No overtly unsafe prescriptions were identified. Conclusion: DeepSeek was able to generate structured, guideline-informed exercise prescriptions across various simulated cardiac rehabilitation scenarios. These results suggest the model's capacity to generate guideline-informed exercise prescriptions aligned with current guideline principles in simulated settings, but they do not prove clinical effectiveness, safety, or suitability for routine practice. Additional studies involving real patients and direct comparisons with clinician-made exercise prescriptions are needed before clinical use can be considered.
