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 (RA) is a chronic autoimmune disease that affects the lining of the synovial joints and approximately affects 0.5 - 1% of the total population imposing a socioeconomic burden. The current study aimed at investigating the novel possible beneficial effects of using zinc oxide nanoparticles (ZnO NPs) on such devastating disease. The complete Freund's adjuvant (CFA) model was used to mimic RA in rats where ZnO NPs were given orally (2 mg/kg/day) daily for 14 days; and diclofenac Na, the standard drug, was given intraperitoneally (1 mg/kg/day) the day after CFA, daily for 14 days. Our results displayed that ZnO NPs attenuated adjuvant-induced increased production of inflammatory mediators interleukin-1β (IL-1β), tumor necrosis factor alpha (TNF-α), interleukin-10 (IL-10), and total leukocyte count. Besides, they ameliorated autoimmunity through suppression of anti-citrullinated protein auto antibodies (anti-CCP) levels in rats. In conclusion our results highlight the benefits which could be obtained of nanoparticles either alone or in combination with the known anti-arthritic and/or anti-inflammatory agents, giving rise to new protocols to maximize the control of RA.
