Post-exercise effects of self-selected exercise intensity on cardiovascular parameters in peripheral artery disease: a randomized crossover study.
Trial report in Einstein (Sao Paulo, Brazil), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04333615 (Effects of Self-selected Walking Exercise Intensity on Adherence, Functional Capacity and Cardiovascular Risk Indicators in Patients With Peripheral Artery Disease), 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
objectiveTo analyze the post-exercise effects of self-selected exercise intensity compared with the intensity recommended by guidelines on blood pressure and heart rate variability in participants with peripheral artery disease.
methodsThis was a randomized crossover trial. Twenty participants with peripheral artery disease (52.6% men; 69.1±7.9 years; ankle-brachial index 0.59±0.15) underwent three experimental sessions: self-selected exercise intensity, intensity recommended by guidelines, and a control session (no exercise). Blood pressure (auscultatory method), heart rate, and heart rate variability were measured before and after the intervention.
resultsAcute reductions in systolic blood pressure were observed in the exercise sessions compared to the control (p<0.005). The heart rate decreased after control and increased after exercise sessions (p<0.001). The absolute heart rate increase after exercise sessions were higher than that in the Control Group p<0.001. Heart rate recovery showed a progressive decrease post-session over 300 s (p<0.001), with the root mean square of successive differences significantly decreasing up to 60 seconds in both exercise sessions (p<0.05).
conclusionAcute walking exercise sessions prescribed at self-selected exercise intensity had similar effects on reducing systolic blood pressure and heart rate recovery compared with walking exercise session performed at the guideline-recommended intensity.
