Association of heart rate recovery with mortality risk in a 72-month survival analysis.
Article in Cadernos de saude publica, 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
This study aimed to investigate whether heart rate recovery (HRR) is a predictor of all-cause mortality in a 72-month survival analysis. In this cohort study, 578 individuals who underwent a maximal exercise test at a university hospital between August 2012 and August 2018 were followed for up to 72 months. Participants performed a maximal incremental treadmill test, followed by an active recovery period phase to evaluate their HRR. When the decay of heart rate totaled ≥ 13bpm in the first minute post-exercise a normal HRR was considered, whereas an abnormal HRR was defined as ≤ 12bpm. Of the 578 individuals, 371 (64.2%) had normal HRR, whereas 207 (35.8%) had an abnormal HRR. The survival analysis showed significantly higher 72-month survival in the normal HRR group (93.8%) than in the abnormal HRR group (81.6%), with a 3.16 hazard ratio (95%CI: 1.86-5.35). Individuals with abnormal HRR were generally older, had a greater burden of comorbidities, shorter time to exhaustion, lower peak heart rate, and higher heart rate 60 seconds after the exercise. Thus, HRR predicted 72-month all-cause mortality. These findings suggest the use of HRR as a simple, non-invasive prognostic tool in clinical practice, particularly for stratifying mortality risk.
