Target and simulated sex- and age-specific prevalence of diagnosed thyroid diseasea.

The target (observed) values were from the NHANES, based on whether the participant reported ever being diagnosed with a thyroid condition or if they were taking one of several thyroid replacement or suppression drugs. See methods section (subheading “Calculation of target tables of disease prevalence”) and Fig 3 for details. The predicted values are of those ever having been treated for functional thyroid disease. See methods and discussion sections (subheading “Likelihood calculations” and “Predicted prevalences” respectively) for details.
