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: Tuina therapy has demonstrated its potential in modulating autophagy-related factors in knee osteoarthritis (KOA); however, its core therapeutic targets and specific mechanisms require systematic elucidation through interdisciplinary research. Objective: This study investigated the mechanism by which Tuina alleviates KOA progression using multidimensional approaches, including Mendelian randomization (MR), in vivo experiments, and machine learning. Methods: Genetic data from genome-wide association studies of 60 cytokines and KOA were analyzed using MR analysis to identify autophagy-related factors significantly associated with KOA. A KOA rat model was established via intra-articular injections of L-cysteine-activated papain solution into the right knee. The key autophagy-related cytokines identified by MR were validated using enzyme-linked immunosorbent assay (ELISA). Cartilage degeneration and autophagic activity were assessed through histological evaluation via safranin O/fast green (SO/FG) staining and ultrastructural analysis via transmission electron microscopy (TEM). A Support Vector Machine (SVM) algorithm was used to conduct a secondary analysis of the experimental dataset to predict comprehensive therapeutic effects and synergistic correlations among the indicators. Results: MR analysis revealed causal relationships between eight cytokines and KOA at genetically determined levels, with seven exhibiting autophagy-related regulatory properties. Tuina significantly alleviated pain and improved motor function. SO/FG staining and TEM revealed reduced cartilage destruction, increased cartilage thickness, and decreased chondrocyte autophagy. ELISA revealed that Tuina downregulated interferon gamma, parathyroid hormone, interleukin (IL)-1β, matrix metalloproteinase-3, and IL-17 levels in the cartilage while upregulating osteocalcin and transforming growth factor-β1 levels. Furthermore, Tuina demonstrated superior comprehensive and classified curative effects compared with celecoxib. IFN-γ and PTH were strongly correlated with both relative autophagy level and cartilage area ratio. Autophagy-related cytokines had the strongest correlation with the degree of cartilage degeneration. Conclusion: Tuina therapy alleviates pain and functional impairment in KOA by suppressing chondrocyte autophagy and delaying cartilage degeneration. This mechanism may involve the regulation of autophagy-related cytokines.
