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
Objective: This study aimed to systematically evaluate the performance of three advanced Chinese large language models (LLMs)-DeepSeek-R1, GPT-4o, and Claude-Sonnet-4-in supporting patient education during post-cardiac surgery rehabilitation. Methods: A total of 35 patient-centered questions were developed based on clinical guidelines, covering five core domains: postoperative care, medication and diet, mental health, complication prevention, and physical activity. Each model was prompted with the same questions five times. Responses were independently assessed by clinical experts for accuracy, completeness, readability (using FRE and FKGL), and reproducibility under repeated prompting. Statistical analyses were conducted using analysis of variance and post-hoc least significant difference (LSD) tests. Results: DeepSeek-R1 demonstrated the highest overall performance in terms of accuracy (mean score: 4.64) and completeness (4.20), and achieved the highest response stability (85.7%). GPT-4o outperformed the others in readability (FRE: 53.19) and linguistic fluency but showed lower reproducibility (62.9%). Claude-Sonnet-4 showed moderate and variable performance, with limitations in clinical detail. All observed differences were statistically significant ( Conclusion: DeepSeek-R1 is most suitable for structured, guideline-based rehabilitation education. GPT-4o may be preferable in emotionally supportive or patient-facing scenarios due to its superior readability. Claude-Sonnet-4, while less consistent, may offer stylistic balance in diverse communication settings. Overall, LLMs show promising potential in digital cardiac rehabilitation, but task-specific model alignment remains essential.
