This study is valuable in that it has long-term (above 5 years) follow-up for SLF. 
1. However, it has some big bias. Even though the two groups have similar characteristics, they have basic
differences that can not be expressed by the simple patients characteristics. The patients in "Long-term
group" might be followed up because they have little problems including recurrence and complications for
5 years or more basically, so this kind of comparison might be have bias. It is thoght to be reasonable that
the same patints would be followed up longitudinally for 5 years or more. 
2. The comparison of Ba, C, and Bp of POP-Q test would be clearer for proving the anterior recurrence. 
3. Backgournd of abstract is too long and difficult to know the purpose of this study, it could be
summarized to kind of "to evaluate the medium and long-term anatomical results and its impact on the
quality of life of SLF".
