Title: Safe discharge for patients admitted for lower gastrointestinal bleeding (LGITB):
derivation and validation of a novel scoring system
Version: 1 Date: 27 Jul 2023
Reviewer's report:
This is a retrospective cohort study with the aim to derive and validate a novel clinical scoring
system to predict safe discharge after LGITB admission. The study design and the statistical
analysis seem to be appropriate, however, I have some suggestions reported below.
• In the method section:
1. The definition of re-bleeding could be improved with references.
2. The Table 1 could be reported in the main text and not like a table, usually Table 1 is referring
to patients’ clinical features.
• The acronyms, especially for those in tables, could be explained at the end of each table.
• It could be useful to keep only the presence of a specific variable for a better reading of Table
2 and Table 3.
• The value of OR reported in Table 4 must be revised, the positive value is referred to a risk
factor not to a protective one.
• The authors demonstrated that the accuracy of the novel scoring system in the prediction of
safe discharge is similar to the accuracy of the Oakland Score. I think that this result may depend
on the poor difference between the two scores, and it could be interesting to focus the future
research on the clinical status of patients.
