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

aimMaternal excess adiposity (i.e., overweight/obesity) is linked to impaired uteroplacental perfusion, compromised placental development, and increased risk of adverse pregnancy outcomes. Inflammation and immune dysregulation accompanying excess adiposity may disrupt leukocyte-mediated tissue remodeling and immunoregulation, contributing to placental dysfunction. However, the impacts of excess adiposity on populations of innate lymphoid cells and macrophages orchestrating these processes, and on the decidual microenvironment, remain understudied. Here, we used a mouse model of high-fat, high-sucrose (HFHS) diet-feeding to study the impacts of excess adiposity on decidual immune dynamics during placental development.

methodsUteroplacental tissues were collected at mid-gestation (E10.5) from mice fed a control chow (CON) or HFHS diet before and during pregnancy. Multicolour flow cytometry was used to profile decidual leukocyte composition. Spiral artery remodeling was measured using (immuno)histochemistry. Multiplex immunoassays were used to compare systemic and decidual cytokine and growth factor levels. Comparative gene expression was measured in placental tissues using a NanoString nCounter array.

resultsHFHS pregnancies had elevated decidual leukocyte abundance, with increased tissue-resident and conventional-like NK cells, and MHC-II

conclusionThese findings point towards decidual vascular inflammation and dysregulated angiogenesis during early placentation in pregnancies complicated by excess adiposity. This may stem from or induce shifts in resident immune cells, contributing to later placental dysfunction.
