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

In this study, p-coumaric acid was evaluated for its immunomodulatory and anti-inflammatory properties in vivo. The immunomodulatory effect of p-coumaric acid (100 mg/kg body weight) was assessed by evaluating its effect on cell-mediated immune responses (delayed type hypersensitivity reaction), serum immunoglobulin levels, and macrophage phagocytic index in rats. The anti-inflammatory effects of p-coumaric acid (100 mg/kg body weight) were investigated by examining its effect on expression of tumor necrosis factor (TNF-α) in synovial tissue by immunofluorescence confocal microscopy and circulating immune complexes in serum of adjuvant-induced arthritic rats. The increased cell-mediated immune responses and macrophage phagocytic index observed in control rats were significantly reduced (p < 0.05) upon treatment with p-coumaric acid implying its immunosuppressive property, whereas serum immunoglobulin levels were found to be increased in p-coumaric acid treated control rats. p-coumaric acid also showed significant (p < 0.05) anti-inflammatory effects in adjuvant-induced arthritic rats by effecting a decrease in the expression of inflammatory mediator TNF-α and circulating immune complexes. Indomethacin was used as a reference drug for anti-inflammatory studies. Thus, our results show that p-coumaric acid could be considered a potential immunosuppressive agent in treating autoimmune inflammatory diseases like rheumatoid arthritis.
