Reviewer's report:
1. General comment 
This is an interesting study, which will attract interest among readers for looking
at pelvic floor dysfunctions and diastasis recti abdominis in postpartum women.
The severity in diastasis recti abdominis is the main point of innovation. There
are points you need to modify as follows. 
2. Specific comments for revision 
1) Line 39 "investigation" should be plural.
2) Line 62 the pelvic floor dysfunction includes pelvic organ prolapse (POP),
urinary incontinence (UI), and sexual dysfunction, why in this study you didn't
described the relationship between DRA and sexual dysfunction?
3) Line 77 you have to add "education status" in the section of methods. How
did you defined "high education" in this study?
4) Line 119It's unclear that "POP-Q≥2" means "stage 2" or "2 cm".
5In this study, the type of urinary incontinence was not considered; it may be
the limitation of the study. It should be described in section of discussion.
