Assessment of aortic and mitral valve regurgitation volumes by cardiovascular magnetic resonance in participants without valvular heart disease in the Hamburg City Health Study population.

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
An assessment of currently available cardiovascular magnetic resonance (CMR) methods to quantify aortic (AR) and mitral regurgitation (MR) in a large, population-based setting is lacking. The aim of this study was to evaluate CMR-based AR and MR quantification methods by quantifying AR and MR in participants without valvular heart disease in the population-based Hamburg City Health Study (HCHS). CMR was performed at 3T in the HCHS population. Aortic valve regurgitation volume (CMR-ARV) was directly obtained from 2D transaortic flow measurements. Mitral valve regurgitation volumes (CMR-MRV) were calculated by subtracting aortic forward flow volumes by Flow CMR from left ventricular stroke volumes by Cine CMR as currently recommended and by a method to account for potential confounding effects of AR on MR calculations (CMR-MRV
