Title: No significant relationship exists between tumor size and prognosis in distant metastatic
hepatocellular carcinoma#a propensity score matching analysis based on SEER database.

Reviewer's report:
To the authors:
“No significant relationship exists between tumor size and prognosis in distant metastatic
hepatocellular carcinoma#a propensity score matching analysis based on SEER database”
My comments are as follows.
1. In the analysis of propensity score matching, how did you set the caliper value and calculate
the propensity scores (mean ± SD)?
2. In the characteristics of the distant metastatic HCC patients, there is only a significant
difference in the T factor, even after propensity score matching. You should re-analyze with the
caliper value lowered.
I hope that my comments will be useful in improving the article.
