Reviewer’s report
Title: 
Comparing neoadjuvant long-course chemoradiotherapy with short-course
radiotherapy in rectal cancer
Version: 
0 
Date: 
25 May 2021
Reviewer's report:
The manuscript is clearly written and there are no problems with english. It is a
good preliminary study that is worthy of publication. 
Corrections needed are:
1. In Fig. 1 the font size of the axes labels is too small and should be increased.
2. Line 287: The sentence does not make sense "when a patient is at risk of
surgical resection margin". Please change it.
