Exercise Capacity (METs)

Higher values go with lower risk of death. Not measured in our NHANES panel. The curve is drawn from the published study (source below).

Risk of death relative to the curve's reference value, drawn from the published study (source below).

Published risk of death0.87×per 1-MET higher level of maximal aerobic capacity (95% CI 0.84–0.90) · Meta-analysis of 33 observational cohort studies of healthy men and women (all-cause mortality: 102,980 participants, 6910 cases)

What studies found when this marker was changed

They describe what happened in those study groups, not a recommendation. See all catalogued interventions.

Measured changes in METs, study by study

1 effect 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.

Each row is one study: what was changed, the effect it reported on this marker, and the source.

What else moves this marker

They describe those study groups, not an individual, and an association is not a cause.
