Effectiveness of Cranberry Supplementation for Prevention and Treatment of Infectious Urinary Tract Disease in Dogs and Cats: A Systematic Review.
Synthesis in Journal of veterinary pharmacology and therapeutics, 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
Cranberry and cranberry extracts are available for treatment or prevention of urinary tract disease in dogs and cats, but guidance regarding their use is lacking. The objectives were to identify and assess literature pertaining to the efficacy of cranberry and cranberry extract supplementation for prevention and treatment of bacterial cystitis and subclinical bacteriuria in dogs and cats. A systematic review was performed, and three studies involving a total of 122 animals (106 dogs and 16 cats) were identified. No studies reported statistically significant or numerical impacts of treatment. Two studies were deemed at high risk of bias, and one was deemed at low risk. Certainty of evidence was low to very low. The small number of studies, small sample sizes, data from those studies, and low certainty of evidence preclude confident assessment of the role of cranberry for the prevention or treatment of infectious urinary tract disease in dogs and cats.
