title: A 3-year evaluation of the TCu380Ag and the Cu-7.
abstract: The TCu380Ag and the Cu-7 intrauterine devices (IUDs) were evaluated in a randomized comparative clinical trial. A total of 198 women who had not recently been pregnant entered the trial in Manila, Philippines and were followed-up through 3 years postinsertion. The 36-month follow-up rates were impressively high at 80.3 for TCu 380A users and 76.7 for users of the Cu-7. Although the two IUDs demonstrated statistically similar termination rates, the findings suggest a higher efficacy for the TCu380Ag. Gross cumulative life-table pregnancy rates were 0.0 and 4.5 for the TCu380Ag and Cu-7, respectively, at 3 years. Overall 3-year continuation rates were 74.3 and 64.9 for users of the respective devices.
