Effects of a Western Diet on Colonic Dysbiosis, Bile Acid Dysmetabolism and Intestinal Inflammation in Clinically Healthy Dogs.
Article in Journal of veterinary internal medicine. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
backgroundConsumption of a high-fat, high-carbohydrate Western-style diet (WD) associated with obesity and inflammation in humans has not been investigated in dogs.
aimsTo determine the effects of WD on inflammatory indices, microbiome, and fecal bile acids (BAs) in dogs. ANIMALS: Ten adult clinically healthy dogs.
methodsA dietary trial compared the effects of two home-prepared diets: a high-fiber, low-fat control diet (CD) to a diet containing the macronutrient composition of WD (low-fiber, high fat). Dietary treatments were given sequentially for three feeding periods, each lasting 1 month. Outcome measures included molecular/microbiologic testing of colonic biopsies, histopathology, inflammatory biomarkers, and quantification of fecal BA following each feeding period.
resultsCell markers of apoptosis (TUNEL-positive cells: CD1, 0.36% ± 0.2%; WD, 0.79% ± 0.5%; CD2, 0.42% ± 0.3%; 95% CI) and inflammation (NF-ĸB area: CD1, 8.09% ± 3.3%; WD, 11.58% ± 3.4%; CD2 7.25% ± 3.8%; 95% CI), as well as serum high-sensitivity C-reactive protein (CD1, 2.0 ± 0.4 ng/mL; WD, 2.76 ± 0.23 ng/mL; CD2, 2.29 ± 0.25 ng/mL; 95% CI), were increased (p < 0.05) in dogs fed WD versus CD. Other perturbations seen with WD ingestion included altered (p < 0.05) colonic mucosal bacteria (bacterial counts: CD1, 301.5 ± 188.5; WD, 769.8 ± 431.9; CD2, 542.1 ± 273.9; 95% CI) and increased (p < 0.05) fecal cholic acid (median and interquartile range/IQR: CD1, 9505 [2384-33 788] peak heights; WD, 34 131 [10 113-175 909] peak heights) and serum myeloperoxidase (CD1, 46.98 ± 16.6 ng/mL; WD, 82.93 ± 33.6 ng/mL; CD2, 63.52 ± 29.5 ng/mL; 95% CI). CONCLUSIONS AND CLINICAL IMPORTANCE: WD fed to clinically healthy dogs promotes colonic dysbiosis, altered fecal BA, and low-grade inflammation independent of obesity.
