Preclinical and Clinical Settings: A Systematic Review and Meta-Analysis

Reviewer's report:
This is a good attempt at a systematic review of resistant starches on IBD in both
preclinical and clinical models. Whilst no meaningful conclusions can be drawn
relevant to practice, the systematic review is a good evidence synthesis of the
literature such as it is and may serve as a suitable platform for further pre-
clinical and clinical research with well-characterised cohorts and using validated
and consistent end-points. As such and given the substantial heterogeneity driven
by study designs and conclusions, I have no major comments criticisms.
Some minor comments to consider:
1.In the introduction where you state that resistant starch is a natural source of
fibre commonly found in many foods, please give examples to the reader.
2.The searches were performed on October 18, 2018 and February 14, 2019,
respectively. Could any studies in 2018-19 therefore have been missed? If there
are other studies they should be included and an updated analysis
performed.Unless your search is "current" through 2019 at the very least.
