Epidemiological data are of little use in guiding clinical practice
Epidemiological studies investigate overall effects within populations,
but clinicians need information about specific risks and benefits for
individual patients. Hannaford and Owen-Smith (p 984) reviewed all
published studies of the risk of cardiovascular disease in current
users of combined oral contraceptives in order to assess the usefulness
of the data in defining the risk for young, healthy women who do not
smoke. Of the 74 papers identified, only five provided information that
directly addressed the clinical question, although 14 others probably
had the potential to answer the question after reanalysis.
