Effect of simethicone on visualization quality and capsule transit time during video capsule endoscopy in healthy dogs.
Article in Journal of veterinary internal medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
backgroundSimethicone enhances visualization quality (VQ) during video capsule endoscopy (VCE) in humans, but its effects on VQ and capsule transit time (CTT) in dogs remain unclear. HYPOTHESIS/
objectivesEvaluate the effects of simethicone on VQ and CTT in dogs undergoing VCE. ANIMALS: Fifteen client-owned healthy dogs weighing 3-10 kg.
methodsProspective, blinded, randomized crossover study. Each dog underwent VCE twice: once with 20 mg (1 mL) simethicone administered 30 minutes before capsule ingestion, and once with 1 mL normal saline as a control. Visualization quality was assessed based on the proportion of mucosa visualized (variable 1), the degree of obscuration by bubbles, debris, blood, or bile (variable 2), and their average (variable 3). Capsule transit time, including gastric transit time (GTT) and small bowel transit time (SBTT), and incomplete study rates also were evaluated.
resultsSimethicone significantly improved VQ in the entire small bowel, especially in the proximal segment (P < .05 for all variables). However, no significant differences were observed between protocols in the distal small bowel and stomach. Gastric transit time and SBTT also were not significantly different between protocols. The risk of incomplete studies was not significantly affected by protocol, sex, body weight, or age. CONCLUSIONS AND CLINICAL IMPORTANCE: Simethicone had region-specific effects on VQ in dogs undergoing VCE, specifically enhancing VQ in the small intestine. These findings provide preliminary evidence of a potential role for simethicone in improving small bowel VQ.
