Kim et al reported a model for predicting an ongoing pregnancy after in vitro fertilization cycles. The authors are from Seoul National University.
Patient selection: in vitro fertilization with embryo transfer
Parameters:
(1) age in years from 26 to 46 years
(2) serum HCG concentration in IU/L from 0 to 650
(3) serum progesterone concentration in ng/mL from 0 to 240
X =
= (0.031 * (HCG)) - (0.228 * (age)) - (0.023 * (progesterone)) + 6.103
probability of ongoing pregnancy =
= 1 / (1 + EXP((-1) * X))
Performance:
• The area under the ROC curve is 0.91.
