Title: Risk assessment of rectal anastomotic leakage (RAREAL) after DIXON in non-
emergency patients with rectal cancer: a retrospective study
Version: 0 Date: 02 Nov 2022
Reviewer's report:
- The authors stated: "All surgeries were performed by experienced and skilled colorectal
surgeons." Please define the minimum number of Dixon operations performed by any surgeons.
- Please replace lower and upper quartiles with first and third, respectively.
- Please replace the incorrect terms 'univariate' and 'multivariate' with 'univariable' and
'multivariable', respectively.
- There is always a loss of information when transforming a continuous variable into a categorical
one. Hence I cannot fully understand the authors' choice to convert HbA1c.
- The final scoring system with instructions should be provided at least in the supplements.
