Data and Methodology
- Dataset
- NHANES 2017-March 2020 Pre-Pandemic ( NHANES 2017-2020 2020 , Primary dataset)
- Survey years
- 2017-2020
- Sample size
- 612 participants
- Reference population
- US civilian non-institutionalized females aged 20-29 from NHANES 2017-March 2020. Includes the full population (not restricted to healthy individuals) to reflect the population distribution.
- Exclusion criteria
-
- Missing serum ferritin measurement (LBXFER)
- Missing or zero MEC sample weight (WTMEC)
- Age outside 20-29 range
- Notes
- Percentiles computed using the combined pre-pandemic MEC weight (WTMECPRP). Serum ferritin measured as LBXFER in ng/mL (Roche Cobas e601 immunoassay). Ferritin rises with inflammation, and this full-population distribution includes participants with inflammatory conditions.
