Right ventricular function in athletes engaged in endurance exercise using speckle tracking echocardiography: a meta-analysis.
Synthesis in BMC cardiovascular disorders, 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
backgroundLong-term endurance training is associated with structural, functional, and biochemical markers of cardiac dysfunction in highly trained athletes. Many studies have focused on structural changes in the right ventricle (RV) and few have examined functional adaptation of the right ventricle. This meta-analysis aims to compare the changes in right ventricular systolic function between endurance athletes and controls before and after exercise using speckle tracking echocardiography (STE).
methodsA comprehensive search of relevant studies published before March 19, 2024 that examined RV systolic function using speckle tracking technology was conducted. Weighted mean differences (WMDs) and 95% confidence intervals (CIs) were used as pooled statistics. Meta regression was employed to identify sources of heterogeneity and publication bias was evaluated by Egger's test and funnel plots. Sensitivity analysis was performed by removing sources of significant change from the results of a single publication to evaluate the stability of the results.
resultsTwenty studies were included with 1186 participants. A fixed effect meta-analysis revealed RV global longitudinal strain (GLS) WMD = 0.40, 95% CI (-0.08 ~ 0.89), p = 0.102 and free wall longitudinal strain (FWLS) WMD = 0.62, 95% CI (0.28 ~ 0.96), p < 0.001, random effect models of RV basal strain WMD = 2.94, 95% CI (2.00 ~ 3.88), p < 0.001 and RV apical strain WMD = -0.79, 95% CI (-1.95, 0.37), p = 0.245 between endurance athletes and controls. In addition, a random-effects meta-analysis revealed significant impairments in RV function when assessed by comparing RV GLS pre-endurance versus post endurance exercise WMD = 2.51, 95% CI (1.634 ~ 3.40), p < 0. 001.
conclusionThe evidence obtained thus far suggests that reporting only global right ventricular strain data may obscure segment-specific adaptation changes, and the use of global and segmental strain analysis may help to identify potential functional changes in the right ventricle while differentiating between normal endurance athletes and non-active controls.
