A comparative study of the clinical performance of two copper-releasing IUDs, Nova-T & Copper-T-200 in Lagos, Nigeria.
A non-randomised study was performed to compare the use-effectiveness of the Copper-T-200 and Nova-T intrauterine devices. It was found that generally, results compared favourably with other world-wide studies. No accidental pregnancies were experienced and no significant difference was found between the expulsion rate of the Nova-T (5.0) and that of the Copper-T-200 (6.5) and the removal rates for bleeding and pain, which were 1.5 and 3.8, respectively. The continuation rate for the Nova-T was 91.3 compared with 88.2 for the Copper-T. The total experience was based on 815 woman-months of use.
