The Right Heart of Elite Male and Female Cyclists: A Comparative Study of Cycling Disciplines.
Article in Journal of cardiovascular development and disease, 2026. 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
backgroundElite cycling can be dichotomised into road (endurance cycling) and track (sprint cycling) events that are associated with different training components and athlete physiology. Evidence of disproportionate right ventricular (RV) remodelling in endurance athletes places importance on defining physiological and athletic phenotypes. Therefore, the elite cyclist serves as an ideal model to study training-specific adaptations in the right heart.
methodsOne hundred and eighty-six (110 males and 76 females) elite international-level cyclists (mean age 23 ± 5 years) were grouped by discipline (endurance cycling and sprint cycling) and sex (male cyclists and female cyclists). RV and right atrial (RA) structure and function was assessed with 2D, tissue Doppler, and strain echocardiography. Structural data were scaled allometrically to body size. Group comparisons were made with a two-way ANOVA.
resultsSignificantly larger absolute and scaled RV and RA structural values were seen in male and endurance cyclists (RV end diastolic area index: male endurance 14 ± 2 cm
conclusionsAthlete sex and cycling discipline exert significant effects on RV and RA structure and function in elite cyclists. The strong correlations observed between endurance training exposure and right heart structure emphasise the importance of consideration of sporting discipline in elite athletes.
