      A comparative study of Norinyl Math Eq and Norinyl Math Eq was conducted at the Dom Zdravlja Stari Grad in Belgrade, Yugoslavia. The study sought to evaluate the differences in continuation rates as well as the frequency of selected side effects which might contribute to method discontinuation. The trial included 299 women who were randomly allocated to one of the two oral contraceptives. In the Norinyl Math Eq group, significantly more women (p<.05) reported a complaint of vaginal discharge as well as an increase in the occurrence of vaginal discharge compared to the Norinyl Math Eq group. There was no significant difference in continuation rates or for particular discontinuation reasons for the Norinyl Math Eq and Norinyl Math Eq groups. No accidental pregnancies were reported during this study. Both oral contraceptives appear to be safe and effective; there appears to be no difference in the acceptability of one oral contraceptive over the other among this group of Yugoslavian women.
