Compared with the general IVF (gIVF) population, the early miscarriage rate was significantly higher in the unLM group (8.28% vs. 13.47%, adjusted odds ratio [OR] 1.60, 95% confidence interval [95% CI] 1.12\u20132.28; <jats:italic>P<\/jats:italic>\u2009=\u20090.01). Furthermore, women in the unLM and ceLM groups had a dramatically increased risk of recurrent LM (unLM: 4.24% vs. 9.43%, aOR 1.91, 95% CI 1.24\u20132.94;
