Reference population
US civilian non-institutionalized males aged 30-39 from NHANES 2017-March 2020. Includes the full population (not restricted to healthy individuals) to reflect the population distribution.
Exclusion criteria
  • Missing blood urea nitrogen measurement (LBXSBU)
  • Missing or zero MEC sample weight (WTMEC)
  • Age outside 30-39 range
Notes
Percentiles computed using survey-weighted analysis (WTMEC weight, divided by 2 to pool two cycles). Blood urea nitrogen measured as LBXSBU in mg/dL.
