Title: 
Comparison of various aspects of women’s lives between infertile and
women with and without tubal ligation: a comparative cross-sectional study
Version:

Reviewer's report:
Although the authors have added a flow chart which adds helpful information
about those who dropped out after recruitment. 
However, the specific concern is
not with how many were deemed ineligible or failed to complete the
questionnaire once they were recruited, the question is about overall response
rate during recruitment - that is, how were the participants approached? 
How
many were approached/asked to participate versus how many actually said "yes"
to the recruitment and were provided with the questionnaires? 
The manuscript
still includes no information about the recruitment protocol and overall response
rates. 
If ONLY 653 were approached and asked to participate, this should be
noted as 100% response rate and 7% dropout and 1% ineligible across groups. 
It
would be very, very unusual for ALL of those approached to agree to participate
in the study. 
If, for example, 2000 women were approached and 653 said "yes"
then this presents a 33% overall response rate and a potential coverage bias that
must be addressed as a limitation. 
Those who said "no" might have been quite
different from those who participated in ways that would impact the findings.
