Influencing factors of unanticipated low ovarian prognosis by using decision tree model
Objective To analyze the influencing factors of unanticipated low ovarian prognosis in infertility patients by using decision tree model.Methods The clinical data of 1 112 patients admitted to General Hospital of Northern Theater Command from January 2017 to December 2021 who underwent in vitro fertilization-embryo transfer were retrospectively analyzed.Patients were divided into low prognosis group and normal response group according to Poseidon criteria.The clinical data of the two groups were compared,in-cluding age,body mass index,infertility years,basal sinus follicle number,basal follicle stimulating hormone,basal luteinizing hor-mone,anti-Mullerian hormone,basal estradiol,gonadotropin initiation,total gonadotropin days and total gonadotropin.Decision tree model was used to analyze the factors affecting the prognosis of unanticipated ovarian hypoplasia.Results Among 1 112 patients,766 were in the normal response group and 346 were in the low prognosis group.Luteinizing hormone,anti-Mullerian hormone,antral follicle number and gonadotropin initiation in low prognosis group were lower than those in normal response group,and age,body mass index,infertility years and follicle-stimulating hormone were higher than those in normal response group,with statistical significance(P<0.05).The decision tree model showed that anti-Mullerian hormone was the root node of the decision tree,and the level of anti-Mullerian hormone was the most important factor affecting the prognosis of unanticipated low ovary.The secondary influencing factors were the number of sinus follicles,initiation of gonadotropin and total gonadotropin.The lowest level of influence factor was body mass index.The accuracy of decision tree model was81.65% .Conclusion The decision tree model can effectively classify patients and determine the degree of impact of different factors on patients,with high accuracy and reference value for decision-making.
