Statistical relationship between different oocyte retrieval groups
| RR (95% CI) (1–5 vs 6–15) | RR (95% CI) (16–25 vs 6–15) | RR (95% CI) (26–49 vs 6–15) | |
| LBR/cycle | 0.53 (0.52 to 0.54); p<0.0001 | 1.09 (1.07 to 1.11); p<0.0001 | 0.58 (0.54 to 0.62); p<0.0001 |
| MGP rate | 0.83 (0.77 to 0.90); p<0.0001 | 1.04 (0.97 to 1.11); p=0.26 | 1.03 (0.84 to 1.26); p=0.77 |
Comparison of main outcome measures depending on the number of oocytes retrieved. The statistical relationships between LBR and MGP and oocytes retrieved.
LBR, live birth rate; MGP, multiple gestation pregnancy; RR, relative risk.
