Title: A novel nomogram and risk stratification system predicting the cancer-specific survival of
patients with gastric neuroendocrine carcinoma: A study based on SEER database and external
validation
Version: 1 Date: 23 Apr 2023
Reviewer's report:
Very interesting study. The statistics is robust and adequate. I have only some minor comments:
1) English grammar should be improved.
2) As all the SEER studies, the analysis lacks of granularity and interpreting some information
is challenging.
3) The nomogram is difficult to interpret due to the very high number of variables.  Could some
of them be grouped? (for example T and N staging)
4) Among the causes of death in these patients, bleeding should be commented (in this regard
