Figure 4: Age-Specific Centiles of NT-proBNP Concentrations Stratified by Race and Ethnicity.

The age-specific 2.5^th, 25^th, 50^th, 75^th, and 97.5^th centiles of N-terminal pro-B-type natriuretic peptide (NT-proBNP) stratified by race and ethnicity have been depicted. Non-Hispanic White, non-Hispanic Black, and Mexican American individuals have been depicted as dotted, dashed, and solid lines, respectively. The 2.5^th, 25^th, 50^th, 75^th, and 97.5^th centiles of NT-proBNP have been depicted in red, yellow, purple, green, and blue, respectively. The inset in the figure shows the 2.5^th, 25^th, 50^th, 75^th, and 97.5^th centiles of NT-proBNP on a magnified y-axis in individuals below 40 years of age.
