Clinical pregnancy rate after the next embryo transfer for the four groups of RIF patients. Group P_e, a positive initial MMP test, but a negative second MMP test after the treatment; Group P_r, a positive initial MMP test, and a positive second MMP test despite the treatment; Group N, a negative response to the MMP test; Group C, the control group who did not undergo the MMP test. Patients in Group P_e had a significantly greater pregnancy rate than patients in Groups N and C (*P < 0.05).
