Next to the name of each questionnaire section, laboratory component, or exam component on the NHANES 2007-2008 data page there are links that appear as follows: [Data, Docs, Procedures]. What are these links for?
In previous years, files for each data section was made available as a self-extracting zip file containing the codebook, documentation, file frequencies, and SAS transport dataset. In addition, each of the codebook, documentation, file frequencies, and SAS transport dataset were made directly, individually accessible by a separate link, in brackets, next to the data section name. Starting with data years 2003-2004, the documentation, codebook, and frequencies have been combined in a single Adobe PDF file, accessible from the single Docs link. A new, direct link to Procedures is also being provided for each data section on the data page. For exam sections this will link to the examination procedures manual for that section, and for questionnaire sections this will link to the questionnaire instrument. Procedure manuals for laboratory sections are also available but as there may be multiple documents for a given lab, these will remain on a separate page, accessible by clicking the Labora
