NOTES: Data sources: (Q) questionnaires; (PE) physical examination; (LAB) laboratory tests; (MRV) medical records verified.

Analyzed endpoints in 1992 study were chosen for ease of comparison with the results from the 1989 CDC Vietnam Experience Study reproductive outcome results. Many of the outcomes in the 1992 report were included under broader variables analyzed for the 1984 and 1998 reports.

Areas in gray indicate that either an endpoint was not analyzed for a particular cycle or that it was unclear from the cycle report if an endpoint was analyzed. Gray areas do not indicate that an endpoint was not measured or recorded for a particular cycle.

aData collected at Cycle 1 (1982). No outcomes verified.

bData collected in 1982, 1985, and 1987.

cBirth defect had to match description on predetermined list to be included in analyses at the baseline.
