Minor comment 8. The authors could clarify whether the SEER nomogram estimates were used to predict outcomes in the external validation set or whether the model was refit using the external data.

Minor comment 9. Some of the DCA lines appear incomplete (Figure 5). The authors could comment on how this relates to the small sample size of the external validation set. For the right-most DCA in figure 5, it is unclear why the nomogram curve has a wider range than the AJCC stage curve. The nomogram uses AJCC stage, so I would think that the curves would have the same range.

以上为审稿人的两个意见

关于8：这个意见啥意思？让我加做外部验证嘛？可是我做了啊（第九条意见也可以看出来我做了外部验证）

关于9：DCA曲线不完整和数据样本量小的关系？？

跪求大神答疑，感激不尽
