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

During pregnancy, invading HLA-G+ extravillous trophoblasts (EVT) play a key role in placental development, uterine spiral artery remodeling, and prevention of detrimental maternal immune responses to placental and fetal antigens. Failures of these processes are suggested to play a role in the development of pregnancy complications, but very little is known about the underlying mechanisms. Here we present validated methods to purify and culture primary HLA-G+ EVT from the placental disk and chorionic membrane from healthy term pregnancy. Characterization of HLA-G+ EVT from term pregnancy compared to first trimester revealed their unique phenotypes, gene expression profiles, and differing capacities to increase regulatory T cells (Treg) during coculture assays, features that cannot be captured by using surrogate cell lines or animal models. Furthermore, clinical variables including gestational age and fetal sex significantly influenced EVT biology and function. These methods and approaches form a solid basis for further investigation of the role of HLA-G+ EVT in the development of detrimental placental inflammatory responses associated with pregnancy complications, including spontaneous preterm delivery and preeclampsia.
