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

Successful embryo implantation occurs followed by a local inflammatory/T helper type 1 (Th1) response, subsequently redirected towards a tolerogenic predominant profile. The lack of control of this initial local inflammatory response may be an underlying cause of early pregnancy complications as recurrent spontaneous abortions (RSA). Considering that vasoactive intestinal peptide (VIP) mediates anti-inflammatory and tolerogenic effects in several conditions we hypothesized that VIP might contribute to tolerance towards trophoblast antigens during the early interaction of maternal leucocytes and trophoblast cells. In this study we investigated VIP/VPAC system activity and expression on maternal peripheral blood mononuclear cells (PBMCs) after interaction with immortalized trophoblast cells (Swan-71 cell line) as an in-vitro model of feto-maternal interaction, and we analysed whether it modulates maternal regulatory T cell (T(reg))/Th1 responses. We also investigated the contribution of the endogenous VIP/VPAC system to RSA pathogenesis. VIP decreased T-bet expression significantly, reduced monocyte chemotactic protein-1 (MCP-1) and nitrite production in co-cultures of PBMCs from fertile women with trophoblast cells; while it increased the frequency of CD4(+) CD25(+) forkhead box protein 3 (Foxp3)(+) cells, transforming growth factor (TGF)-β expression and interleukin (IL)-10 secretion. These effects were prevented by VIP-specific antagonist. Interestingly, PBMCs from RSA patients displayed significantly higher T-bet expression, lower T(reg) frequency and lower frequency of VIP-producer CD4 lymphocytes after the interaction with trophoblast cells. Moreover, the patients displayed a significantly lower frequency of endometrial CD4(+) VIP(+) cells in comparison with fertile women. VIP showed a Th1-limiting and T(reg) -promoting response in vitro that would favour early pregnancy outcome. Because RSA patients displayed defects in the VIP/VPAC system, this neuropeptide could be a promising candidate for diagnostic biomarker or surrogate biomarker for recurrent spontaneous abortions.
