corded or measured in AFHS clinical and laboratory evaluations or those obtained from private medical and dental records or military records.

The myriad laboratory tests performed (by the Kelsey-Seybold Clinic for Cycle 1 and Scripps Clinic for Cycles 2–6) on subject blood, urine, and semen were provided by AFHS investigators by committee request and are listed in Table B-14. Dioxin assays are not included in this list as they were performed separately at the Centers for Disease Control and Prevention.

A summary of covariates used in various analyses throughout the AFHS is provided in Table B-15 to further characterize available subject data.

Table B-16 provides a brief overview of the types of data gathered through questionnaire administration as well as the major changes made to questionnaire (baseline and interval) content over time.

Additional details relating AFHS data resources and analyses are can be found in Chapters 24.
