Table 3.
In vitro fertilization outcomes for all analyzed samples, and for samples classified into two groups based on their telomere length (shorter or longer than the median); total n indicates the total number of embryos including all samples, % represents the average percentage of the parameter analyzed: p-values indicate statistical differences of the % between groups with shorter and longer telomere length. (*) means p ≤ 0.05.
