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

Extracellular vesicles (EVs) are key mediators of maternal-foetal communication, regulating placental function and foetal development through the transfer of bioactive molecules. Although placental EVs play a crucial role in placental function during pregnancy, their contribution to foetal development, notably foetal brain, remains poorly understood. Human cytomegalovirus (HCMV) is the most common virus transmitted in utero and a leading cause of infectious brain malformations. Although certain central nervous system lesions caused by HCMV are explained, the neuropathogenesis of congenital infection remains poorly understood. In this study, we demonstrate that EVs from healthy placentas promote neurogenesis. However, EVs from HCMV-infected placentas lose this neurogenic potential, impairing differentiation and migration of neural stem cells, perturbations that may contribute to the neurodevelopmental defects observed in congenital HCMV infections. miRNA profiling revealed profound infection-induced changes, including the incorporation of viral miRNAs and dysregulation of host miRNAs involved in neurogenesis. These findings highlight the critical role of placental EVs in foetal brain development and their contribution to HCMV neuropathogenesis.
