Reviewer's report:
Title "Self-administered subcutaneous medroxyprogesterone acetate for
improving contraceptive outcomes: a systematic review and meta-analysis" 
Overall, it was well structured and well written. The quality of the work reflexes
the knowledgeable of the authors regarding the methodology in a systematic
review and meta-analysis. However, there are some opinions below that require
your attention to make your article much better.
* There are minor grammatical errors throughout the manuscript. Please let the
native English speaker proofreads your article one more time. 
* Objectives (Page 5, Line 27-32), I think your objective should be rewritten
cause the sentence is redundance and make your objectives less clear. 
* PRISMA statement released the latest version of recommendation in 2020. The
structures under each section in 2020 PRISMA statement does differ from the
2009 version you use. Please update the structure of manuscript as the updated
PRISMA statement. 
* You cover in all aspects of PRISMA statement. Obviously, there are more
study needed regarding self-administered DMPA-SC.
