R-CKGAT: a recommendation algorithm based on scientific fitness knowledge graph.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
In recent years, with the spread and popularization of health knowledge, more and more people have begun to participate in fitness exercises to strengthen their bodies and prevent diseases. However, due to the lack of fitness knowledge base and the imperfection of fitness recommendation algorithm, fitness enthusiasts cannot obtain accurate fitness knowledge. Therefore, how to recommend personalized content for users according to their preferences has become a practical topic. Therefore, based on the knowledge graph technology, this paper constructs the scientific fitness knowledge graph, and proposes a model R-CKGAT that integrates collaborative knowledge embedding, user preference propagation and knowledge graph attention mechanism. Experimental results show that compared with MF, CKE and other baseline algorithms, the AUC and ACC values of the proposed algorithm in the scientific fitness data set are better than those baseline algorithms. The AUC and ACC of the model were 92.76% and 88.67% correspondingly.
