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
Chondrocyte abnormalities play an important role in osteoarthritis (OA), and forkhead box C1 (FOXC1) expression is related to OA progression. Nonetheless, the molecular mechanisms underlying the action of FOXC1 in chondrocytes remain unclear. Rats were subjected to anterior cruciate ligament transection (ACLT) to establish an in vivo OA model, and chondrocytes were subjected to interleukin (IL)-1β to establish an in vitro OA model. Pathological changes in rat cartilage tissues were evaluated using hematoxylin-eosin and safranin O staining. H3K27Ac enrichment in the FOXC1 promoter was analyzed using chromatin immunoprecipitation. Interactions between EP300 and Y-box binding protein 1 (YBX1) were validated using RNA immunoprecipitation and RNA pull-down assay. The expression of YBX1, EP300, and FOXC1 was elevated in ACLT rats and IL-1β-induced chondrocytes. FOXC1 knockdown inhibited apoptosis and inflammatory response in IL-1β-induced chondrocytes. EP300 bound to FOXC1 promoter and promoted H3K27Ac enrichment in the FOXC1 promoter. Additionally, YBX1 bound to EP300 mRNA and enhanced EP300 mRNA stability. YBX1 overexpression promoted cell apoptosis and inflammation of IL-1β-induced chondrocytes, but was reversed by FOXC1 downregulation. YBX1 enhances EP300 mRNA stability and elevates FOXC1 expression by mediating FOXC1 H3K27Ac to promote IL-1β-induced chondrocyte apoptosis and inflammation, thereby exacerbating chondrocyte injury in OA.
