2. FIGURE 1
Cumulative live birth and dropout rate after IVF/ICSI as function of treatment cycle number. The live births are subdivided into singletons in the black bands, twin births in blue bands, and triplet births in yellow bands. Patients continuing treatment are in gray bands and patients that stopped further treatment are in red bands.

Live birth rate per cycle (light blue bars) and cumulative live birth rate per patient (dark blue bars) for the LUMC cohort and the “transport clinic” cohort. a Results are significantly different (P<.001).

5. FIGURE 4
Relation of the observed cumulative live birth rate and the overestimation factor. Results after a follow-up period of 3 cycles are shown by the red line; a follow-up of 5 or more cycles is represented by the blue line. Data points refer to Table 5. A = the data from this study.
