1 · What the graph read from it

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.

2 · The registry

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

Objectives: Exercise improves cardiovascular health in older adults, yet variability in responsiveness remains. This study tested if prescribed exercise intensity adherence predicts individual differences in cardiovascular fitness gains following an intervention. Methods: From 2017 to 2022, nineteen sedentary older adults (69.78 ± 6.47 years) completed a 12-week aerobic cycling program in the Exercise Research Laboratory at the Atlanta VA Hospital. Participants trained 3× weekly, progressing from 20 to 45 min per session. Target intensity, expressed as percent heart rate reserve (HRR), increased from 50% to 80%. Cardiovascular fitness ( Results: Estimated Conclusions: Cardiovascular adaptations in older adults relate more strongly to prescribed HR adherence than attendance. Objective, trajectory-based adherence metrics may refine exercise prescriptions and improve prediction of individual responsiveness.
