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

Aedes aegypti mosquitoes transmit arboviruses that pose a growing global health threat. After a bloodmeal, mosquitoes experience complex physiological changes orchestrated by the midgut and fat body, beginning with digestion and culminating in egg production. Our study provides comprehensive midgut and fat-body cell atlases using single-cell RNA sequencing and metabolomics. Our analyses reveal highly diverse cell populations specialized in digestion, metabolism, immunity, and reproduction. The midgut primarily comprises enterocytes, enteroendocrine, and intestinal stem cells, while the fat body features trophocytes and oenocytes but also a substantial hemocyte population and a newly found fat-body-yolk cell population. Additionally, Phasi Charoen-like virus was detected in midgut cells 7 days post bloodmeal. These findings highlight the complexity of mosquito abdominal tissues and inform the development of refined vector-control strategies, focusing on specific cell populations and metabolic pathways essential for mosquito reproductive success.
