Gut microbial ammonia enhances colonic acetylcholine levels to regulate intestinal motility.

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.
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
Intestinal motility is a function of the enteric nervous system involving secretion of the excitatory neurotransmitter acetylcholine (ACh). Although gut commensal bacteria are key regulators of intestinal physiology, the molecular mechanisms underlying microbial influence on intestinal peristalsis and constipation remain unclear. Here we report a link between microbial nitrogen metabolism and intestinal motility regulation via ammonia production. We observed compensatory elevation of intestinal ammonia levels and urease activity in mouse models of intestinal dysmotility, induced by ACh deficiency, and in patients with constipation. Ammonia supplementation or intervention in mice with the urease-positive Lysinibacillus fusiformis isolated from patient stool, or engineered urease-expressing bacteria, effectively restored colonic ACh levels. In vitro, ammonia upregulated the expression of voltage-gated calcium channels on enteric neurons, driving Ca
