OR: Odds Ratio; 95% CI: 95% confidence interval; p: significance value. Binary logistic regression model adjusted for maternal age (<35, 35-38, >38), oocyte type (Own vs. Donated), embryo quality (excellent/good vs fair/poor), and KIDScore/IDAScore algorithm value (<7 vs. ≥7). Group 0 was used as a reference for the main variable (expansion change group).
