Note: Data are presented as mean (± SD), median (IQR) or number (%).
a
The difference between the pseudo‐timeline LH day and the actual LH day (ΔLH) or LH + 7 (ΔWOI). Due to missing data on actual LH day, two samples in the Ongoing pregnancy group and three samples in the No pregnancy group were excluded, leaving 31 and 49 samples, respectively.
b
Two‐sided Wilcoxon rank sum test.
c
One‐sided Wilcoxon rank sum test.
