Growth Differentiation Factor-15 (GDF-15)

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

GDF-15 and risk of death

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

Published risk of death2.52×highest vs lowest GDF-15 category (95% CI 2.06–2.97) · Meta-analysis of 31 prospective studies, 53,706 subjects, 7020 adverse outcome events (mixed general and CVD-patient cohorts)

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 GDF-15, study by study

2 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.

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