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

objectivesTo evaluate the effects of Allium cepa (A. cepa) on levels of oxidants, antioxidants, and immunological markers in bronchoalveolar lavage fluids (BALF) of sensitized rats. MATERIALS AND

methodsOxidant/antioxidant markers and cytokines in BALF of control rats treated with saline (group C), ovalbumin-sensitized rats (group S), rats treated with 1.25 μg/mL dexamethasone and 3 doses of A. cepa extract (35, 70, and 140 mg/kg body weight [BW]/day) (S + AC) were investigated. Comparison of the results between groups was performed using analysis of variance with the Tukey-Kramer post hoc test.

resultsThe oxidant markers nitrogen dioxide (NO2), nitrate (NO3-), and malondialdehyde (MDA), and immunological markers interleukin (IL)-4 and immunoglobulin E (IgE) were significantly higher, but the antioxidant markers superoxide dismutase (SOD), catalase (CAT), thiol, and interferon (IFN)-γ, and the IFN-γ/IL-4 ratio were lower in sensitized rats compared to control rats (p < 0.001 to p < 0.01). Compared to group S, the levels of the following markers were significantly lower: NO2, NO3-, and IgE in groups treated with the A. cepa extract, MDA and IL-4 levels in groups treated with 70 and 140 mg/kg BW/day of the A. cepa extract, and all these markers as well as IFN-γ in rats treated with dexamethasone (p < 0.001 to p < 0.05). However, there were significantly higher levels of SOD and CAT and an increased IFN-γ/IL-4 ratio (groups treated with 70 and 140 mg/kg BW/day of the A. cepa extract), and levels of thiol and IFN-γ (group treated with 140 mg/kg BW/day of the A. cepa extract) as well as SOD, CAT, and thiol (dexamethasone-treated group) versus group S (p < 0.00 to p < 0.05).

conclusionA. cepa showed antioxidant and immunomodulatory properties in sensitized rats.
