3. Figure 2
Kaplan-Meier plotting of the cumulative live birth rates (CLBR) of at least one baby, depending on the total number of consumed oocytes and categorized by age (≤35 y and ≥36 y). Overall comparisons: log rank (Mantel-Cox); P=.003; Tarone-Ware; P=.011. The table shows the CLBRs and 95% confidence intervals (CsI) when 5–15 oocytes were consumed, according to age.

Elective fertility preservation (FP) trends regarding the total number of oocyte vitrifications (vit.) for other reasons in our group. The plotting shows the total number of elective FP (EFP) cycles. ∗All of the metaphase II (MII) vitrification cycles at all clinics involved. ∗∗Percentage of EFP cycles among the total MII vitrification cycles.
