- Survey years
- 2017-2020
- Sample size
- 937 participants
- Reference population
- US civilian non-institutionalized males aged 40-49 from NHANES 2017-March 2020. Includes the full population (not restricted to healthy individuals) to reflect the population distribution.
- Exclusion criteria
-
- Missing potassium measurement (LBXSKSI)
- Missing or zero MEC sample weight (WTMEC)
