Abstract
A comparative randomized trial was carried out on two intrauterine contraceptive devices: the Nova-T and the MLCu375. The IUDs were used by 1116 and 1237 women respectively, over a period of 2 years. The reasons for IUD removal were analyzed after one and two years using the life-table method. Statistically significant differences were found in the rates for pregnancy, expulsion and removal for bleeding and/or pain favoring the MLCu375 IUD.
Resumé
Une étude comparative randomisée a été effectuée sur deux dispositifs contraceptifs intrautérins: le Nova-T et le MLCu375. Ces stérilets ont été utilisés respectivement par 1116 et 1237 femmes sur une période de deux ans. On a analysé après un an et après duex ans, par la méthode des tables de survie, les raisons pour lesquelles ces DIU avaient été abandonnés. Des différences significatives du point de vue statistique ont été constatées dans les taux de grossesse, d'expulsion et de retrait pour cause de saignement et/ou de douleurs, et ces différences étaient favorables au dispositif MLCu375.
Resumen
Se hizo una prueba comparativa al azar de dos dispositivos anticonceptivos intrauterinos: el Nova-T y el MLCu375. Los DIU fueron usados por 1116 y 1237 mujeres respectivamente, durante un período de 2 años. Las razones para quitar un DIU fueron analizadas después de uno y dos años de uso empleando el método de tabla de vida. Se encontraron diferencias estadísticas significativas en las tasas de embarazo, expulsión y remoción por sangrado y/o dolor, siendo favorables para el MLCu375.
