Title: Clinicopathological characteristics and prognosis of signet ring cell carcinoma of the
gallbladder
Version: 1 Date: 24 May 2021
Reviewer:  Feng Wei
Reviewer's report:
In the previous review proposal, I suggested that the authors add propensity score matching
(PSM). The authors have added the PSM data in the revised manuscript. Here is a small problem
that the CS analysis of Figure 2A in the revision is consistent with Figure 2 in the first manuscript.
Is the CS analysis result in Figure 2 based on before or after PSM?
