Acute Versus Chronic Ischemic Mitral Regurgitation: An Echocardiographic Study of Anatomy and Physiology.
Article in Circulation. Cardiovascular imaging, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 12 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
backgroundLittle is known on the mechanism of acute ischemic mitral regurgitation (IMR) caused by sudden-onset left ventricular dysfunction in acute myocardial infarction (MI). We sought to investigate the mitral valve (MV) complex geometry in acute IMR in comparison with chronic IMR by 2-dimensional and 3-dimensional transthoracic echocardiography. METHODS AND
resultsForty-four first-onset acute MI and 36 previous MI with ≥moderate IMR were examined by 2-dimensional/3-dimensional transthoracic echocardiography. MV morphology was quantitatively analyzed and compared between the 2 groups. Left ventricular end-diastolic volume and left ventricular end-systolic volume were significantly smaller in acute IMR than in chronic IMR (40.8 [33.1-48.3] versus 88.8 [66.5-108.8] mL/m
conclusionsSudden-onset left ventricular dysfunction in acute MI may cause loss of coaptation of the MV even with a relatively mild degree of valve tethering. Compared with previously studied chronic IMR, a smaller leaflet area without leaflet adaptation and a larger hemodynamic burden at the acute onset of MI could result in clinically significant IMR despite relatively small leaflet tethering.
