Round  1

Reviewer 1 Report

To my mind, this new version of the manuscript has significantly been improved by the authors:

The authors have included a "material and methods section" with a clear flowchart (inclusion and exclusion criteria) as any systematic review needs to present.

I am still missing the specific "question" the authors wants to answer based on their objective search and posterior analysis. This may be the reason why their final selection is too wide with 134 papers.

Still, after the material and methods section, the paper is presented as a "narrative review" and in this format reads as a very nice piece with interesting blocks of information and could be accepted for publication (even if the present manuscript may not follow the "orthodoxal" structure of a systematic analysis). In this case, the authors should coment and cite at the introduction section previously published systematic reviews already linking gut bacteria and ASD (see below). This would allow the authors to highlight (and readers to differentiate) the new additions of present review paper when compared with previous similar literature.
