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

BACKGROUND AND

objectiveMaggots are the larval stage of

methodsMice were randomly assigned to five groups (n=6/group): normal, AR, Maggot, AR+ Maggot, and AR+ dexamethasone (DXM). The Total Nasal Symptom Score (TNSS), ovalbumin (OVA)-sIgE titers, histopathological characteristics and Th1-/Th2-/Th17-related cytokine levels were evaluated. The expression of T-bet, GATA3, RORγt and Foxp3 in the spleen and nasal mucosa of mice was detected, and the proportion of differentiated Tregs in the spleen of mice was determined. In addition, the effects of maggot extracts on the expression level of Foxp3 and the differentiation of Tregs in vitro were studied. Histological evaluation of the potential toxicity was also performed.

resultsCompared with the AR group, the AR+ Maggot group showed reduction in histopathological inflammation, downregulated OVA-sIgE titers, and restoration of the imbalance in cytokine profiles (P<0.05). After treatment with maggot extracts, the proportions of Tregs and Foxp3 expression in the spleen were significantly increased, the expression of GATA3 and RORγt was decreased (P<0.05), and the expression of T-bet showed no significant change (P>0.05). In vitro, maggot extracts promoted the expression of Foxp3 and differentiation of Tregs in a dose- and time-dependent manner (P<0.05). In addition, no obvious organ damage was observed in mice treated with maggot extracts.

conclusionMaggot extracts can inhibit the progression of AR by upregulating the level of Foxp3 and promoting the differentiation of Tregs, thus serving as an alternate treatment for AR.
