Heart Rate Recovery (1 min)
Higher values go with lower risk of death. No risk curve catalogued yet.
Published risk of death1.09×per 10 beats per minute decrement in HRR (lower HRR = higher risk) (95% CI 1.01–1.19) · Meta-analysis of 9 prospective cohort studies of HRR and all-cause mortality in the general population (41,600 participants, 2082 deaths)

Measured changes in 1 min, study by study
4 effects with a numeric size, each from one study arm: the dot is the reported change, the line its 95% interval where one was given. Green points move the marker the way lower risk of death lies; amber the other way. Study results in the groups studied, not predictions for a person.
