Right Heart Cardiac Magnetic Resonance Profiles and Cardiopulmonary Reserve in Older Adults Undergoing Long-Term Multicomponent Exercise: A 2-Year Longitudinal Study.
Article in Scandinavian journal of medicine & science in sports, 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
Right heart geometry and function are essential for preserving physical performance in healthy aging, yet evidence regarding how long-term supervised multicomponent exercise influences right heart characteristics and cardiopulmonary reserve over time remains limited. To address this gap, this interim analysis of a prospective, non-randomized, two-armed cohort study included 155 adults aged ≥ 65 years assigned to supervised multicomponent training (n = 75) or education control group (n = 80). Cardiac magnetic resonance imaging and cardiopulmonary exercise testing were performed at baseline, 1-year, and 2-year follow-ups, with right heart structure and function as the primary outcomes; post hoc analyses were stratified by training adherence. Among these participants, 92 (training: n = 54; control: n = 38) completed the 2-year follow-up and were included in the final analysis. No significant time × group interactions were detected for right or left heart parameters (all p > 0.05). After multivariable adjustment, the exercise group showed higher overall adjusted mean values for right atrial volumes and selected right ventricular functional measures, including stroke volume, cardiac index, and peak filling rate (all p < 0.05). In contrast, significant time × group interactions were identified for peak VO
