Pregnancy outcomes were ascertained by chart review. In addition to its substantive contribution to knowledge about birth defects, the study further demonstrated the research capabilities of KP, enhanced the reputation of KP in the community, and contributed to the development of an infrastructure for conducting research in KP Northern California.
Attempts were also made to limit oral contraceptive use to women who were not at high risk for vascular disease because Alabama big booty smoking or hypertension, for example.

The study of stroke and myocardial infarction was followed by an identically deed study that assessed the risk of venous thromboembolic disease in users of low-estrogen-dose oral contraceptives.
