1 · What the graph read from it

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.

2 · The registry

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

Rheumatoid arthritis is a chronic inflammatory disease characterized by overproduction of inflammatory mediators along with undermined oxidative defensive mechanisms. Pathological angiogenesis was found to play a critical role in the progression of this disease. The current study was carried out to evaluate the anti-angiogenic, anti-inflammatory, and anti-oxidant effects of evening primrose oil (EPO), rich in gamma linolenic acid (GLA), either alone or in combination with aspirin or celecoxib, on adjuvant-induced arthritis. Arthritis was induced by subcutaneous injection of complete Freund's adjuvant (CFA) in the right hind paw of male albino rats. All treatments were administered orally from day 0 (EPO, 5 g/kg b.w.) or day 4 (celecoxib, 5 mg/kg; aspirin, 150 mg/kg) till day 27 after CFA injection. In the arthritic group, the results revealed significant decrease in the body weight and increase in ankle circumference, plasma angiopoietin-1 (ANG-1) and tumor necrosis factor-alpha (TNF-α) levels. Anti-oxidant status was suppressed as manifested by significant decline in reduced glutathione content along with decreased enzymatic activity of superoxide dismutase and increased lipid peroxidation. Oral administration of EPO exerted normalization of body weight, ANG-1, and TNF-α levels with restoration of activity as shown by reduced malondialdehyde levels. Moreover, histopathological examination demonstrated that EPO significantly reduced the synovial hyperplasia and inflammatory cells invasion in joint tissues, an effect that was enhanced by combination with aspirin or celecoxib. The joint use of GLA-rich natural oils, which possess anti-angiogenic, anti-inflammatory, and anti-oxidant activities, with traditional analgesics represents a promising strategy to restrain the progression of rheumatoid arthritis.
