All metrics were evaluated on dataset 2 (D3) blastocysts transferred on day 5 after preimplantation genetic testing for aneuploidy. Values are shown as mean ± SD for all folds in the five-fold cross validation.
AUC, area under the receiver operating characteristic curve; F1, the harmonic mean of the precision and sensitivity.
