Summary
In 1977, a field study was started, in which randomly selected gynecologists should recruit five pairs of patients each, a pair consisting of a pilltaker and an age-matched control between 16 and 35 years. 51.9% of the physician sample contributed a total of 373 patient pairs. Each patient should get a medical examination and complete a questionnaire at the start and after one year. Complete information was received in 59.2% of all pairs. Adherence to the recruitment criteria was fairly close at the beginning. After one year 27.5% of the pairs were split up by a change of contraception. Two major features of the study design should therefore be newly assessed in the future: If possible, one should recruit individuals rather than pairs. Social data should be collected through a separate organization.
