A randomized comparative study of three IUDs: Nova-T, MLCu375 and MLAgCu250 in New Zealand: 1-year results.
A randomized comparative study was made in New Zealand of three models of copper IUDs, the Nova-T, MLCu375 and MLAgCu250, with interval acceptors. At 1 year, the Multiloads (MLs) had lower net termination rates for accidental pregnancy, expulsion, pain/bleeding, other medical removals and infections (use-related terminations) than the Nova-T. These rates were significantly lower for the MLAgCu250 than the Nova-T for accidental pregnancy, expulsion and infection. The MLCu375 had significantly fewer removals for pain/bleeding and for other medical removals than the Nova-T. The MLAgCu250 had a significantly lower accidental pregnancy rate than the MLCu375. The Multiloads had significantly higher relevant use-related continuation rates than the Nova-T.
