Title: Validation of the Swedish version of the EORTC LMC-21, the disease-specific
questionnaire for assessing health- related quality of life in patients with colorectal liver
metastases
Version: 5 Date: 14 Jan 2025
Reviewer:  David T. Eton
Reviewer's report:
Introduction. In the second paragraph, the authors state: "Surgery has become more aggressive
to improve radicality."  What does this mean?  What is "improving radicality?"
Results, first paragraph: It is hard to know which questionnaire items are being referred to here
by the numbers provided.  Have the authors included an appendix with the questionnaire that
includes the numbered items so that it is obvious to readers which items they are referring to?
This is also true for a few paragraphs in the Discussion.
Results, last paragraph: The correlation test statistic should be identified as rho (Spearman's non-
parametric rho), not Pearson's r (a parametric statistic). The statistical analysis section identifies
Spearman's correlation as being used to establish concurrent validity.
