Imaging of the equine abdomen using point of care ultrasound (POCUS): Effects of sedation on intestinal motility in horses.
Article in Australian veterinary journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
backgroundPoint of care ultrasonographic (POCUS) assessment of the equine abdomen is now readily available to the equine practitioner using hand-held ultrasound transducers. Commonly used medications may alter the sonographic appearance or function of the small intestine, caecum or colon.
aimTo demonstrate qualitative and quantitative effects of xylazine sedation on intestinal motility of healthy horses using hand-held, wi-fi ultrasound transducers and validate POCUS methodology by determination of intra- and interobserver agreement. METHODOLOGY: Double-blind cross-over study of eight healthy horses using hand-held, wi-fi ultrasound transducers to determine the effects of sedation on intestinal motility in comparison with administration of a placebo (saline). Motility was independently assessed by three observers using deidentified videos obtained using hand-held, wi-fi ultrasound transducers. Agreement was assessed by determination of intraclass correlation coefficient (number of duodenal contractions) and weighted kappa statistic for motility grades.
findingsSedation was associated with fewer duodenal contractions (median 0.5, range 0 to 2) after sedation, compared with administration of saline (median 4, range 3 to 5, p < 0.001). Large colon and composite motility grades were also reduced (median 4.5, range 2 to 6 after sedation; median 10, range 7 to 12, after saline, p = 0.005), and qualitative changes were evident in the sonographic appearance of jejunal loops in six of eight horses. Interobserver agreement was moderate to good, and intraobserver agreement was good to excellent.
conclusionPOCUS proved to be an effective tool to recognise qualitative and quantitative changes associated with sedation.
