NOTE: Data were adjusted using the Iowa State University method to provide estimates of usual serum potassium concentrations. Means, standard errors, and percentiles were obtained using C-Side. Standard errors were estimated via jackknife replication. Each standard error has 49 degrees of freedom. Females who had “blank but applicable” pregnancy or lactating status data or who responded “I don’t know” to questions on pregnancy or lactating status were excluded from the analysis.
