Title: Development and validation of nomograms for predicting overall survival and cancer-
specific survival in elderly patients with locally advanced gastric cancer: a population-based
study
Version: 1 Date: 09 Dec 2022
Reviewer's report:
This paper establishes a nomogram to predict the survival of elderly patients with gastric cancer.
After verification, this nomogram shows excellent predictive power. But there are still some
places that need to be modified by the author, such as:
1. There may be some language problems that make it difficult for people to understand. Take
the last sentence of the Results section of the summary.
2. Advise to change reference 15 to the recommended reference format on the SEER official
website, that is, the recommended reference format displayed at the bottom of the SEER*Stat
software when the database is selected.
3. It is suggested to conduct statistical difference analysis on the baseline data in Table 1.
4. Interestingly, in Table 5, the C-index of training cohort is smaller than that of internal and
external verification, which is worthy of careful code and data checking by the author.
5. Suggest that the author add the line number for the convenience of the reviewer to mark.
6. It is suggested that the drawing of Figure 6 refer to IDO 10.1186/s12876-020-01464-z, IDO
10.1186/s12876-021-01692-x.
