P, progesterone; 17-OHP, 17-hydroxyprogesterone; Values are mean ± SEM or n (%).
Index 1 = measurements on the day of FET, Index 2 = one week later, at the time of second visit.
P-values of the longitudinal comparison confront the characteristics on the day of FET and on the day of the second visit.
