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

objectiveAcid-sensing ion channels are proton-activated ion channels predominantly found in the nervous system. They are well known to affect metabolic and neurological health, yet their role in obesity and gut physiology remains unclear. This study investigates how systemic deletion of Asic1a influences obesity, metabolic, and gut-based outcomes.

methodsEmploying male and female rats with systemic Asic1a deletion (Asic1a

resultsOn a chow diet, Asic1a deletion resulted in significant gains in body weight, fat mass, glucose intolerance, and insulin resistance in both male and female rats compared to wild-type controls. These effects were exacerbated with high-fat diet administration. Asic1a

conclusionsResults provide evidence that ASIC1a plays a role in regulating metabolic homeostasis and the gut microbiota impacting body composition.
