title: Mortality among women participating in the Oxford/Family Planning Association contraceptive study.
abstract: 43 deaths are known to have occurred among the 17 032 participants in the Oxford/Family Planning Association contraceptive study up to the end of April, 1977. 9 deaths from cardiovascular causes have been observed among the women in the oral-contraceptive entry group (49 681 woman-years of observation) while no such deaths have been observed among the women who entered the study while using a diaphragm or an intrauterine device (39 146 woman-years of observation). These findings are consistent with the results presented in the accompanying report from the Royal College of General Practitioners Oral Contraception Study.
