Abstract

Eight-hundred patients recruited between September 1981 and December 1984 were admitted to a randomized prospective trial of the Nova T (NTCu200Ag) and Multiload 250 (MLCu250) IUDs. At the cut off date, 31 December 1986, 206 patients had completed the 4-year trial period, 379 had terminated before completion and 215 were in the fourth year of use. For the third and fourth years, the MLCu250 had a significantly lower accidental pregnancy rate (p < 0.05).

Resumé

Huit cent patientes recrutées entre septembre 1981 et décembre 1984 ont été retenues pour un essai prospectif randomisé sur les dispositifs Nova T (NTCu200Ag) et Multiload 250 (MLCu250). A la date finale, le 31 décembre 1986, 206 femmes s'étaient soumises aux conditions de l'essai pendant les 4 années prévues, 379 l'avaient abandonné avant la fin et 215 étaient dans la troisième ou la quatrième année d'utilisation. Le taux de grossesses accidentelles pour la troisième et la quatrème années années était significativement moins élevé dans la cas du dispositif MLCu250 (p<0.05).
