| Group | Oocytes thawed | Oocytes survived | Survival rates% (RR; IC 95%) | MII oocytes with analyzable spindle | Normal MII oocytes | Meiotic normality rate % (RR; IC 95%) |
|---|---|---|---|---|---|---|
| Fresh | N/A* | N/A | N/A | 78 | 55 | 70.5 (REF)† |
| ING | 178 | 145 | 81.5 (REF) | 69 | 36 | 52.2 (0.740; 0.566-0.967) |
| T4 | 176 | 154 | 87.5 (1.09; 0.997-1.192) | 82 | 52 | 63.4 (0.899; 0.723-1.119) |
| Total | 354 | 299 | 84.5 | 229 | 143 | 62.4 |
Note: Comparisons between groups was performed with chi-square test. p value <0.05. The relative risk (RR) followed by the confidence interval was estimated to quantify the possible association between the groups. Data presented as percentage; relative risk and confidence interval (%; RR; IC 95%). *N/A: not analyzed. †REF is the control.
