Clinical study: Cardiovascular outcomes after a 14-week exercise intervention in young adults born preterm.
Article in Pediatric research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03504215 (Exercise Intervention to Rescue the Adverse Effect of Preterm Birth on Cardiovascular and Pulmonary Health), which is not on this 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.

Abstract
backgroundPreterm birth has long-term consequences including higher cardiovascular disease risk. We previously reported the effect of an exercise intervention on cardiorespiratory fitness in young adults born preterm at <30 weeks' gestational age) and term. This article reports on cardiovascular outcomes.
methodsThis single-arm clinical trial tested a 14-week exercise program: two 90-min in-person sessions/week (cardio, resistance, flexibility) and one 30-min at-home cardio session/week. Cardiovascular parameters were measured pre- and post-intervention. Term-born individuals were included to validate the intervention.
resultsSixteen preterm and 30 term participants completed pre- and post-visits. Both groups improved peak circulatory power and cardiac output index (COi) and COi reserve during cardiopulmonary exercise testing (CPET). Nocturnal blood pressure (BP) dipping and other CPET-related hemodynamic improvements occurred only in term participants. Reductions in 24-hour and awake BP, heart rate, and hypertensive loads were observed in preterm participants, but not the term participants, who exhibited elevated or hypertensive BP values pre-intervention.
conclusionAn exercise intervention can improve cardiovascular health in preterm and term born individuals. Additional BP benefits were observed in preterm participants with elevated or hypertensive BP. These indicate that cardiovascular changes associated with preterm birth are, at least partially, amenable to improvement through lifestyle intervention. CLINICALTRIALS: gov ID: NCT03504215 URL: https://clinicaltrials.gov/study/NCT03504215 . IMPACT: A structured exercise intervention improves cardiovascular function and blood pressure in young adults born very preterm. This study demonstrates that cardiovascular alterations associated with preterm birth are not fixed in early adulthood and can be improved through exercise. Notably, individuals born preterm with elevated or hypertensive blood pressure experienced significant blood pressure reductions following the intervention. Exercise-based lifestyle interventions may represent an effective, non-pharmacological strategy to reduce long-term cardiovascular risk in adults born preterm.
