Retrospective Evaluation of Transcatheter Edge-To-Edge Mitral Valve Repair in Dogs With Myxomatous Mitral Valve Disease.
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 3 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
backgroundTranscatheter edge-to-edge repair (TEER) is an emerging minimally invasive mitral valve repair treatment for dogs with myxomatous mitral valve disease (MMVD), but reports on its outcomes are limited.
objectiveDescribe the clinical characteristics and complications in dogs with MMVD undergoing TEER. ANIMALS: Twenty client-owned dogs with MMVD stages B2, C, and D.
methodsRetrospective case series. Cases were identified by review of hospital medical records between September 2023 and September 2024.
resultsTwenty dogs underwent TEER; of these, 13 (65%) survived. Seven dogs died within 9 days because of mitral leaflet tear or single-leaflet device attachment (4/7 dogs, 57.1%), tracheal collapse (1/7 dogs, 14.3%), presumed post-procedure neurologic deficit with a history of hydrocephalus (1/7 dogs, 14.3%), and presumed cardiogenic shock (1/7 dogs, 14.3%). Significant reductions in vertebral heart score (11.6 [9.6-13.1] vs. 11.0 [8.3-11.9] vertebrae; p < 0.01), vertebral left atrial size (2.90 [2.1-3.6] vs. 2.60 [2.0-3.3] vertebrae; p < 0.01), left atrium-to-aortic root ratio (2.09 [1.5-2.5] vs. 1.69 [1.3-2.2]; p < 0.05), left ventricular end-diastolic diameter normalized for body weight (2.1 [1.5-2.3] vs. 1.76 [1.4-2.2]; p < 0.05), regurgitant fraction (77.83 [73.2-83.0] vs. 55.38 [20.5-73.6] %; p < 0.05), and regurgitant volume (3.96 [2.1-6.2] vs. 1.25 [0.4-3.5] ml/kg; p < 0.05) were observed 3 months after TEER. CONCLUSIONS AND CLINICAL IMPORTANCE: Transcatheter edge-to-edge repair resulted in a significant reduction in left atrium and ventricle size and should be further investigated as a potential treatment option for dogs with MMVD.
