title: The effect of oral contraceptive formulation and field-workers: a cautionary tale.
abstract: This paper examines oral contraceptive continuation rates and reported side effects in a large scale clinical research project conducted in Sri Lanka. The project evaluated standard- and low-dose pills used with and without vitamin supplements. Differences in continuation rates and perception of side effects are used to illustrate the impact that family planning field-workers can have on women's use of oral contraceptives.
