Supplementation of Vitamin K1 in Dogs With Chronic Enteropathy.
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. 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
backgroundInformation regarding measurement and supplementation of vitamin K1 (vitK1) in dogs with chronic enteropathy (CE) is limited. HYPOTHESIS/
objectivesCompare vitK1 concentrations of healthy dogs to dogs with CE and determine if supplementation with vitK1 increases vitK1 concentrations compared to placebo. ANIMALS: Twenty client-owned dogs with CE and 20 healthy university-owned research colony dogs.
methodsProspective, randomized, placebo-controlled study. Dogs with CE were randomly assigned to receive placebo or vitk1 2.5 mg/kg PO q12h for 3 weeks. Vitamin K concentrations were measured pre- and post supplementation using liquid chromatography tandem mass spectrometry and compared to vitK1 concentrations in the healthy cohort.
resultsAll healthy dogs had initial vitK1 median concentrations of 0.10 ng/mL (interquartile range [IQR], 0.05), which was similar to dogs that received either placebo (n = 5; 0.10 ng/mL; IQR, 0.05) or vitK1 (n = 7; 0.10 ng/mL; IQR, 0.05) before supplementation. Dogs with CE receiving vitK1 had increased vitK1 concentrations (12.5 ng/mL; IQR, 4.1) after 3 weeks of supplementation compared with baseline (0.10 ng/mL; p < 0.001), placebo group after 3 weeks (0.10 ng/mL; p < 0.0001) and healthy dogs (0.10 ng/mL; p < 0.004). CONCLUSIONS AND CLINICAL IMPORTANCE: Oral supplementation with vitK1 increased vitK1 concentration in the serum of dogs with CE, but a clinical benefit from increased vitK1 concentrations was not identified. The absence of difference in vitK1 concentrations between healthy and CE dogs before supplementation requires additional investigation.
