Embryo Density and Its Neutrality in Day-3 Embryo Development: A Retrospective Cohort Study

Figure 3

Relationship between embryo density and cleaving speed of day-3 embryos in different models. The analysis was performed by GEE (generalized estimate equation) model, subject ID = patient unique medical record number (independence). (a) Crude model: no factor was adjusted; (b) Model I: the number of retrieved oocytes and AMH were adjusted; (c) Model II: maternal age, paternal age, maternal BMI, type of infertility, type of insemination, COS protocol, AMH, the number of retrieved oocytes, length of stimulation, antral follicles, incubator, and culture medium were adjusted.
