Comparison Between the Effect of Mid-Late-Life High-Intensity Interval Training and Continuous Moderate-Intensity Training in Old Mouse Hearts.
Article in The journals of gerontology. Series A, Biological sciences and medical sciences, 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
The impact of mid-late-life exercise on the aging heart remains unclear, particularly the effects of high-intensity interval training (HIIT) and continuous moderate-intensity training (CMIT). This study was the first to examine cardiac function, tissue characteristics, electrical remodeling, mitochondrial morphology, and homeostasis in old mice subjected to CMIT or HIIT, compared to untrained controls. Our results showed that 8-week HIIT significantly improved the survival rate of old mice. HIIT presented advantages on cardiac function, deposition of collagen fibers, neovascularization, aging biomarkers, and mitochondrial homeostasis. Only CMIT alleviated age-related cardiac hypertrophy. However, CMIT potentially exacerbated adverse cardiac electrical remodeling. Those findings suggested HIIT as a particularly appealing option for clinical application for aging populations.
