Among the limited number of reports on progestin-oral contraceptives (POCs), noncomparative studies conducted at family planning clinics have been the most often reported. This research trend will probably continue. Generally, noncomparative studies address a number of practical issues on POC use, and such studies have made important contributions to the understanding of this contraceptive modality. However, some studies have presented results that are either difficult to extrapolate for potential users or conflict with other findings. This article reviews several studies and suggests ways to improve the study methodology. Well-conceived, -executed, and -analyzed noncomparative studies can cost-effectively address a number of practical issues of POC use that have not been adequately addressed. Additional topics with programmatic utility, such as the effect of local background variables on POC acceptability, and the place of POCs in the ever-increasing contraceptive spectrum, are also discussed.
