Overall accuracy of the artificial intelligence tool for blastocyst expan- sion, inner cell mass and trophectoderm quality on the test and training data

Morphological feature	Training	Test
Blastocyst expansion	93.9	81.5
Inner cell mass	93.0	78.8
Trophectoderm	78.8	78.3

Data are presented as the percentage of correct predictions between the AI tool and the conventional approach by embryologists.
