title: A randomized comparative trial of the Lippes Loop D, Gravigard and TCu 220C IUDs.
abstract: This randomized prospective trial compared the use-effectiveness and pregnancy rates in 3 IUDs following immediate postabortal insertion in 199 women over 3107 months of use.  At 24 months the Gravgard (Cu 7) was not significantly different from either of the other 2 devices.  However, the Lippes Loop D when compared with the TCu 220C had a higher expulsion rate (P less than 0.05) and a higher use-related termination rate (P less than 0.001).  Further details of accidental pregnancies, removal for incomplete abortion or pelvic inflammatory disease and within 48 hours after insertion are presented.
