Placental cytotrophoblast microvillar stabilization is required for cell-cell fusion.

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.
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
The placenta is an essential organ of pregnancy required for maternal-fetal transport and communication. The surface of the placenta facing the maternal blood is formed by a single giant multinucleate cell: the syncytiotrophoblast. The syncytiotrophoblast is formed and maintained via fusion of progenitor cytotrophoblasts. Cell-cell fusion is a tightly regulated process, and in non-trophoblastic cells is accompanied by stereotypical alterations in cell shape by cells that have attained fusion-competence. The most prominent feature is the formation of actin-based membrane protrusions, but whether stereotypic morphological changes occur in fusion-competent cytotrophoblasts has not been characterized. Using a human placental explant model and trophoblast organoids, we identify microvilliation as a morphological feature that is enriched prior to fusion of cytotrophoblasts. Disruption of microvilli using an inhibitor of the actin-membrane cross-linker protein ezrin blocked cytotrophoblast fusion in both models. We provide evidence that cytotrophoblast microvilli are enriched in early endosomes and a pro-fusogenic protein. Thus, we propose that the polarized assembly of microvillar domains is crucial for mediating efficient syncytiotrophoblast development.
