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
introductionRheumatoid arthritis (RA) is an autoimmune disease pathologically characterized by synovial inflammation. The abnormal activation of synoviocytes seems to accompany the progression of RA. The role and exact molecular mechanism in RA of columbianadin (CBN) which is a natural coumarin is still unclear.
objectivesThe present research aimed to investigate the effect of vimentin on the abnormal growth characteristics of RA synoviocytes and the targeted regulatory role of CBN.
methodsCell migration and invasion were detected using the wound healing and transwell method. Mechanistically, the direct molecular targets of CBN were screened and identified by activity-based protein profiling. The expression of relevant proteins and mRNA in cells and mouse synovium was detected by western blotting and qRT-PCR. Changes in the degree of paw swelling and body weight of mice were recorded. H&E staining, toluidine blue staining, and micro-CT were used to visualize the degree of pathological damage in the ankle joints of mice. Small interfering RNA and plasmid overexpression of vimentin were used to observe their effects on MH7A cell proliferation, migration, apoptosis, and downstream molecular signaling.
resultsThe TNF-α-induced proliferation and migration of MH7A cells could be significantly repressed by CBN (25,50 μM), and the expression of apoptosis and autophagy-associated proteins could be modulated. Furthermore, CBN could directly bind to vimentin and inhibit its expression and function in synoviocytes, thereby ameliorating foot and paw swelling and joint damage in CIA mice. Silencing and overexpression of vimentin might be involved in developing RA synovial hyperplasia and invasive cartilage by activating VAV2 phosphorylation-mediated expression of Rac-1, which affects abnormal growth characteristics, such as synoviocyte invasion and migration.
conclusionCBN-targeted vimentin restrains the overactivation of RA synoviocytes thereby delaying the pathological process in CIA mice, which provides valuable targets and insights for understanding the pathological mechanisms of RA synovial hyperplasia.
