Note: TQE: top-quality embryo; OR: odds ratio; CI: confidence interval. developmental stage: cleavage versus blastocyst stage, PEª was defined as an unordered categorical variable according to progesterone levels: <0.50, 0.50-074, 0.75-0.99, 1.00-1.24, 1.25-1.49, 1.50-1.74, 1.75-1.99 and ≥2.00 ng/ml. The 95 % CIs of developmental stage bPE were all covered 1
