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

objectiveRepeated pregnancy loss has been shown to be related to decidual immune imbalance. Metformin has been found to promote a shift in the Th17/Treg balance towards immune tolerance. Our research aims to evaluate and obtain further information on the role and potential mechanism of metformin on Th17/Treg balance in the early pregnancy decidua.

methodsDecidual immune cells from normal pregnancy women were treated with metformin, pro-inflammatory cytokines or metformin + cytokines respectively. The mRNA expression levels of STAT3, STAT5, RORC and Foxp3 were detected by qRT-PCR. The proportions of Th17 and Treg cells, the stability of Treg cells, and the STATs phosphorylation levels of T cells were evaluated by flow cytometry. The cytokine concentrations in the culture medium were detected by ELISA.

resultsAfter treated with metformin, indicators related to immune tolerance, including the mRNA expression and phosphorylation levels of STAT5, mRNA expression level of Foxp3, the proportion of Treg cell, and the IL-10 concentration increased significantly. Indicators related to immune rejection including the mRNA expression level of STAT3, the proportion of Th17 cell, and the IL-17A concentration showed a significant decrease. In inflammatory conditions, the proportion of Th-like Treg cells increased. Metformin promoted CD25 expression to maintain Treg cell stability.

conclusionMetformin has beneficial effects on immunological tolerance at the maternal-foetal interface in early pregnancy. The underlying mechanism may be that metformin restores the Th17/Treg balance by changing the expression of STATs, which is conducive to establishing maternal-foetal immune tolerance.
