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
objectiveTo investigate the role of NF-AT5, an osmoprotective transcription factor, in synovial hyperplasia and angiogenesis in patients with rheumatoid arthritis (RA).
methodsThe expression of NF-AT5 in synovial tissue and synoviocytes from RA patients was examined by immunohistochemistry and Western blot analysis, respectively. Messenger RNA (mRNA) in RA synoviocytes and human umbilical vein endothelial cells (HUVECs) transfected with dummy small interfering RNA (siRNA) or NF-AT5 siRNA were profiled using microarray technology. Assays to determine synoviocyte apoptosis and proliferation were performed in the presence of NF-AT5 siRNA. VEGF₁₆₅-induced angiogenesis was assessed by measuring the proliferation, tube formation, and wound migration of HUVECs. Experimental arthritis was induced in mice by injection of anti-type II collagen antibody.
resultsNF-AT5 was highly expressed in rheumatoid synovium, and its activity was increased by proinflammatory cytokines, such as interleukin-1β and tumor necrosis factor α. The mRNA profiling of synoviocytes and HUVECs transfected with NF-AT5-targeted siRNA revealed 3 major changes in cellular processes associated with the pathogenesis of RA: cell cycle and survival, angiogenesis, and cell migration. Consistent with these results, NF-AT5 knockdown in RA synoviocytes and HUVECs inhibited their proliferation/survival and impeded angiogenic processes in HUVECs. Mice with NF-AT5 haploinsufficiency (NF-AT5(+/-)) developed a very limited degree of synovial proliferation, as seen on histologic analysis, and decreased angiogenesis, and they exhibited a nearly complete suppression of experimentally induced arthritis.
conclusionNF-AT5 regulates synovial proliferation and angiogenesis in chronic arthritis.
