Title: Clinical outcomes of surgical resection versus radiofrequency ablation in very-early#stage
hepatocellular carcinoma: A propensity score matching analysis
Version: 1 Date: 13 Oct 2021
Reviewer's report:
I have the following comments:
1) Which method was used for propensity score matching? reading the paper i suppose authors
used the nearest neighbour method but his should be specified.
2) why a caliper of 0.02 was used?
3) i have some concerns on the collinearity of some variables used for the propensity score
matching (particularly, cirrhosis and albumin.....)
4) Was there any impact of eventual post-treatment adjuvant therapies? in this regard, cite the
paper PMID: 25974743
5) The concept of post-recurrence survival after radical therapies should be at least mentioned
in the discussion. In this regard, cite the study PMID: 25085684
