2. Figure 1
Comparison of morphologic stage, grade, and aneuploidy rates in day 5 embryos. Logistic regression model was used for the statistical analysis. Embryo number, maternal age, and stimulation protocol type were all controlled for in the calculations. P<.05 between morphologic stages at each grade.

3. Figure 2
Morphologic stage, grade, and aneuploidy rates in day 5 and day 6 stratified embryos. Logistic regression analysis was performed. Embryo number, age, day 5 embryo transfer, and stimulation protocol type were all controlled for in the calculations. The five categories of embryos were described as follows: 1) day 5 blastocyst; 2) day 6 blastocyst–day 5 other (embryos that became blastocysts on day 6 but had not yet reached morula stage on day 5); 3) day 6 blastocyst–day 5 morula (day 5 morulas that progressed to blastocysts); 4) day 5 morula–no blastocyst (day 5 morulas that did not blastulate); and 5) day 6 morula.
