Analysis of Regional Right Ventricular Function by Tissue Doppler Imaging and Three-Dimensional Echocardiography in Highly Trained Athletes.
Article in Journal of cardiovascular echography. 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
backgroundRegional right ventricular (RV) function has not yet been characterized in highly trained athletes, and the effects of increased RV volumes on resting changes of regional RV deformation are unknown. PURPOSE: The aim of the study was to analyze global and regional RV function by a multisegmental approach using tissue Doppler imaging (TDI) and to determine whether higher RV volumes evaluated by three-dimensional echocardiography (3DE) had an impact on the RV mechanics assessed by resting regional TDI parameters.
methodsWe enrolled prospectively 25 professional soccer players and 25 age- and sex-matched nonathletic controls. Transthoracic echocardiography including additional views of the RV was performed. The TDI sample volume was placed in the basal region of the anterior, inferior, and RV free wall to assess the following parameters: isovolumic contraction time (IVCT
resultsIn athletes, LV mass index/body surface area (BSA), left atrial volume index, 2D LV volumes/BSA were significantly increased in comparison with controls. Moreover, athletes had higher 2D LV and RV stroke volume (SV), lower values for A wave and E/e' ratio, higher basal RV diameter, and right atrial (RA) area (
conclusionsIn athletes, the higher 3D RV volumes are proportionally related to an increase of IVRT
