Is there a link between blastomere contact surfaces of day 3 embryos and live birth rate?

Table 2 Mean and SD of contact surfaces of embryos resulting in a live birth

Number of embryos resulting in live birth	115 (24)
Mean contact surface (±SD) of the total group of transferred embryos	19708.2. (±7238.53) pixels
Mean contact surface (±SD) of embryos resulting in live birth	18945.5 (±5670.9) pixels
Ideal range	13274.6-24616.4 pixels
Total number of embryos within ideal range	341
Total number of embryos outside ideal range	133
Positive predictive value	27%
Negative predictive value	83%
Sensitivity	80%
Specificity	31%
Area under the curve	0.56

Based on these data, the “ideal” range of the contact surfaces of the embryos was defined. The total group of embryos was subdivided into two groups based on having the contact surface within or outside the defined range. PPV, NPV, sensitivity, specificity and ROC were calculated.
