^aModel predicting fertility preservation procedure only includes those who had a consultation.

^bSignificance level corresponds to ^*p < 0.05, ^**p < 0.01, and ^***p < 0.001.

^cNo female patients underwent any fertility preservation procedure during the study time period; the variable sex was removed from the analyses.

CI, confidence interval.
