This table displays the survey weighted proportion of healthy individuals from NHANES survey cycles 1999–2004, partitioned by sex and age category, with an NT-proBNP measurement equal to or above the preselected values of 125 and 450 ng/L. 95% confidence intervals were calculated using the variance-stabilizing arcsine square root transformation for the binomial distribution, subsequently expressed on the probability scale.
