Association of mean levels of circulating GDF-15 and clinical and genetic determinants. Error bars in each panel represent standard errors. A. Circulating mean levels of GDF-15 by Framingham risk score quartiles. B. Circulating GDF-15 levels by rs888663 genotype. GDF-15 levels were estimated (back-transformed from log-transformed data) and estimated allele frequency within FHS, error bars represent standard errors.
