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 is a primary vector for many significant human pathogens. Maltase 1 (MAL1), a key enzyme in carbohydrate metabolism, hydrolyzes maltose to release glucose, which participates in sugar metabolism. Currently, there are no studies on the involvement of MAL1 in the regulation of viral infections in arthropods. The expression of MAL1 in Ae. aegypti significantly decreases after DENV2 infection. In this study, we used CRISPR/Cas9 technology to generate a MAL1 knockout strain of Ae. aegypti. The absence of MAL1 significantly suppressed DENV2 replication and transmission throughout the infection process in mosquitoes. At the same time, it reduced the hatching and pupation rates but increased the emergence rate. The absence of MAL1 extended the survival time of male Ae. aegypti while reducing the survival time of females. The results indicate that MAL1 affects arbovirus replication, transmission, and various stages of the Ae. aegypti life cycle.
