OBJECTIVE: To compare ectopic pregnancy (EP) rates among users of non-medicated and copper-containing IUDs.
STUDY DESIGN: The number of women with non-medicated and copper devices were 3491 and 11,682, respectively. Cumulative woman-months of use (CWMU), Pearl Index (PI) and gross cumulative lifetable EP rates for 1000 women were calculated.
RESULTS: The numbers of users at the end of the 10th year were 550 and 569 for non-medicated and copper-containing IUDs, respectively. CWMU for plastic and copper devices was 191,678 and 473,533, respectively, at the 169th month of maximum follow-up. The PIs were 0.8 and 1.0 calculated for 1000 users per year. The gross cumulative lifetable EP rates for 1000 women were 1.4 and 0.9 at 12 months, and 6.8 and 8.9 at the end of the 10th year, respectively, for the plastic and the copper IUDs.
CONCLUSION: Although the rates were lower for the plastic IUD in the majority of the observations, there were no statistically significant differences between the two groups.
