What statistical information is given for each biochemical indicator in the report?
The nutrition report presents descriptive statistics about the distribution of blood or urine levels of biochemical indicators in the U.S. population. Statistics include geometric means and selected percentiles with confidence intervals. Percentiles provide additional information about the shape of the distribution. The report presents 10th and 90th percentile levels for a biochemical indicator when the sample size was too small for 5th and 95th percentile levels in several subgroups. Data are presented for the total population as well as by age, sex, and race or ethnicity.
