Title: Development and validation of a prognostic nomogram for gallbladder cancer patients
after surgery
Version: 4 Date: 24 Mar 2022
Reviewer:  Zhisong Liu
Reviewer's report:
Although the new graph can catch the median for overall survival, but it still cannot reflect its
confidence interval. My suggestion is to add the confidence interval to the graph. On the one
hand, it can correspond to the content described in the article. On the other hand, doing so can
make the graph richer and reflect more information. Survminer is a helpful package. You may
see the link below for an example.
