Histopathological and immunohistochemical characteristics of chordae tendineae affected by degenerative processes in canine myxomatous mitral valve disease.
Article in Veterinary research communications, 2025. 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
Myxomatous mitral valve disease is a major problem in canine cardiology. Degenerative changes extend from the valve leaflets to reach the rest of the subvalvular apparatus. The chordae tendineae (CT) play a key role in the mechanics of the mitral valve and ensure unidirectional blood flow through the heart. Degenerative changes within the chordae tendineae can severely disrupt their function, ultimately leading to an episode of chordae rupture. The study aimed to analyse the structure of healthy and degenerated CTs via histopathology and immunohistochemistry. The mitral valve was assessed macroscopically using the Whitney scale to identify degenerative changes. The chordae tendineae were classified on a four-grade scale (0-3) on the basis of structural changes and subsequently analysed through immunohistochemical staining with antibodies targeting collagens I, III, and IV, as well as fibronectin, chondroitin, and tenascin. The findings revealed alterations in the extracellular matrix in degenerated chordae tendineae.
