How are continuous NHANES data (1999-present) organized in the publicly accessible website?
• The current NHANES data are first grouped into survey cycles (i.e. 2005-2006, 2003-2004, 2001-2002, 1999-2000); • Within each cycle, the date files are organized into four major components: Demographic, Examination, Laboratory, and Questionnaire files; • Survey variables are stored in these different components, and the component’s variable list contains the list of all the publicly released variables and their file locations.
