A multidimensional approach reveals the function of lactylation related genes in osteoarthritis.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
As a complex joint disease, osteoarthritis (OA) increasingly affects the elderly. Currently, existing drugs cannot cure OA. There is an urgent need for new targets. Lactylation is closely related to inflammation and is an emerging target in treatment. However, the potential of lactylation-related genes (LRGs) in OA is poorly understood. This study identified differentially expressed lactylation-related genes (DELRGs) through bioinformatics analysis, constructed a model through a combination of various machine learning methods, and performed immune infiltration analysis, single-cell analysis and molecular docking to predict drugs. Mendelian randomization was used to study the causal relationships between eQTLs and the three types of osteoarthritis. Finally, we used RT-qPCR and CCK-8 assays to validate the results of the bioinformatics analysis. We generated a model with good diagnostic efficacy and seven hub genes, which revealed that osteoarthritis is associated with the infiltration of immune cells such as dendritic cells and macrophages, as well as with the cell communication between fibroblasts and macrophages. Azacitidine, with significant docking results, was obtained through seven hub genes. The results of RT-qPCR verified the expression of LRGs and CCK-8 assay indicated that azacitidine can significantly inhibit the proliferation of OA cells. Overall, we established a lactylation-based diagnostic model and obtained novel biomarkers, which are expected to lead to the development of new strategies for the diagnosis and treatment of OA.
