Title: Comparison of fully coated anti-reflux metal stenting and per-oral endoscopic myotomy
in patients with achalasia: a propensity score- matched retrospective study
Version: 5 Date: 03 Nov 2021
Reviewer's report:
I have the following suggestions to improve the manuscript:
1) More details on how the PS model was built should be added. The term "capacity" should be
replaced by the more appropriate term "caliper".
2) In this regard, why a 0.1 caliper was used? THis is not in accordance with the standard
recommandations of the statisticians who suggest a caliper of 0.2 of the log of the propensity
score (Austin et al).
3) How were normality assumptions assessed?
4) A figure reporting propensity score jitter or histogram should be added.
5) In the discussion, i recommend to add the following recent references on achalasia:
- PMID: 34447872
- PMID: 34222636
- PMID: 32856150
6) In the introduction (or in the Discussion), the authors should mention briefly that POEM can
be used also in esofageal conditions other than achalasia. In this regard, cite the paper:
- PMID: 34608024
