Prediction of pregnancy outcome in fresh in vitro fertilization/intracytoplasmic sperm injection treatment in patients with poor ovarian reserve
Figure 1. Association between pregnancy outcome and female age, treatment cycles, duration of Gn used and transferable embryos in "unexpected" group. A threshold, nonlinear association between pregnancy outcome and these independent predictive factors was found (P<0.05) in a generalized additive model (GAM). Solid rad line represents the smooth curve fit between variables. Blue bands represent the 95% of confidence interval from the fit. Pregnancy outcome was defined as live birth rate; Gn.
