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
In spite of popularity of TNF-α antagonist in the treatment of rheumatoid arthritis (RA), their modes of action are not fully understood. In the present study, we further explore the effects of gene transfer route of a TNF-α antagonist on arthritis. Recombinant adeno-associated virus 2 (rAAV2) encoding rat TNF receptor-immunoglobulin Fc (ratTNFR:Fc) fusion gene was injected intraarticularly in rats with collagen-induced arthritis (CIA). As revealed by examination of the clinical, radiographical, and histological aspects, local gene transfer of rAAV2/ratTNFR:Fc ameliorated the arthritis symptoms and inhibited the development of CIA. Compared with the vector control group, expressions of TNF-α, IL-1, and IFN-γ were down-regulated, and IL-10 release was up-regulated in the rAAV2/ratTNFR:Fc-treated group. Furthermore, administration of rAAV2/ratTNFR:Fc ameliorated the enlargement of spleen and significantly reduced spleen cell proliferation. Low level of nitric oxide (NO) in spleen was observed in CIA rats following the delivery of rAAV2/ratTNFR:Fc when compared to the vector control group. This study provides the evidence that intraarticular delivery of rAAV2/ratTNFR:Fc suppress the progression of arthritis by restoring the balance between pro-inflammatory and anti-inflammatory cytokines and inhibiting spleen cell proliferation. Our findings also implicate that the down-regulation of NO release on arthritis is involved in the anti-inflammatory mechanisms of TNF-α antagonist.
