Abstract

A steady flow of epidemiologic reports concerned with the benefits and risks of different contraceptive methods began in the mid-1960s and has continued unabated ever since. Christopher Tietze soon realized the need to put the findings in perspective by conducting a “medical audit.” The results of his work, using what he described as a “simple paper and pencil model,” appeared in 1961.1
