Figure 1.

The relationship among clinical characters (age, BMI, E2, P, EMT and GQR) from patients undergoing embryo transfer. (A) Correlation matrix of 6 features. The blue and red squares show positive correlations and negative correlations, respectively. Color depth is positively correlated with correlation coefficient. (B–F) Comparison between features. BMI, body mass index; EMT, endometrial thickness on the day of progesterone treatment; GQR, good-quality embryo rate; E2, serum estradiol level on the day of embryo transfer; P, serum progesterone level on the day of embryo transfer.
