Subgroup analysis
Stratified by age
The cumulative livebirth rate stratified by age between the groups was
shown in Figure 2. In women aged 20 - 33 years old, the cumulative
livebirth rate of the salpingectomy group was significantly higher than
the neosalpingostomy group (Figure 2-C, p<0.001), while in women aged
34 - 45 years old, the difference did not reach statistical significance
(Figure 2-D, p = 0.373).
