Fig. 4

Illustration of the predicted probability of pregnancy after transfer of embryos originating from 10 patients of clinic A, where a double embryo transfer (DET) was performed. Patients were selected according to at least a 30% pregnancy chance predicted by our model A (according to morphokinetic parameters and female age), of both embryos. The light blue and dark blue bars represent the individual predicted probability of pregnancy after single embryo transfer (SET) for the first and second embryo. The white dots indicate the predicted probability of a twin pregnancy after transfer of both embryos originating from one patient; the black dots indicate the predicted probability of a singleton pregnancy after DET. Abbreviations: DET, double embryo transfer; SET, single embryo transfer
