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

Epiblast lumen formation is a critical step that occurs during human embryo implantation. It begins with the apicosome, an apical compartment partly derived from endocytosed material. However, how the endo-lysosomal system contributes to apicosome formation and later lumen development remains unclear. Using a human pluripotent stem cell-derived model of epiblast formation, we show that apicosome formation is accompanied by transient expansion of early endosomes, late endosomes, and lysosomes, as well as the formation of hybrid compartments with features of both early and late endo-lysosomal stages. These changes depend on the RAB GTPases RAB35 and RAB7, which are required for proper apicosome formation and lumen morphology of the human epiblast model. Our findings identify RAB35- and RAB7-dependent endo-lysosomal remodeling as a key mechanism driving apical membrane morphogenesis during human epiblast development.
