Table 5.

Prediction rate of ‘Day 3’ PGS analysis (based on one cell diagnosis) on the entire embryo status at ‘Day 4’. Prediction was considered as “true” when either both results were normal or abnormal, or when ‘Day 3’ result was abnormal and ‘Day 4’ result was mosaic (since it also classifies the embryo as abnormal). “True” predictions are marked in the highlighted squares

‘Day 3’ diagnosis (Single cell analysis)	‘Day 4’ diagnosis (Average of 12.1 cells)
	2n	Mosaic	Abnormal
2n	6.3 %	25 %	0 %
Abnormal	12.5 %	37.5 %	18.7 %
