Predicted pregnancy and multiple pregnancy rates for the collaborative model for three transferred embryos, as a function of implantation rate. In each block, the lower line corresponds to singleton pregnancies, the upper line to the total pregnancies, the area to the multiple pregnancies and the black area to the triplet rate.
