Objectivity and consistency among embryologists in embryo assessments. The cumulative frequency charts show the distribution of embryos based on quality scores assigned by embryologists along with the distribution of their developmental grades, and scores generated by the deep-neural network using embryo images recorded at (A) 70 hpi (n = 748) and (B) 113 hpi (n = 742). Dotted lines represent the individual distributions, and bold lines represent the consensus. The scores 1–5 represent the different embryo quality grades in increasing order; score 0 represents categorization when an embryologist was uncertain about the quality grade of an embryo.
