Reviewer's report:
A good systemic meta-analysis about the role of Fecal Calprotectin in diagnosis
and staging of colorectal neoplasia by Fiona A and colleagues. 
Despite not a clear cut conclusion, I appreciate this work and systemic review. 
I request the authors to follow the exact role of a meta-analysis study and revise
the manuscript accordingly.
1. There is no introduction in the abstract. Replace the current sentence and
explain few sentences about FC and CRC.
2. Revise miss abbreviations and capitalizations. In the abstract, result section,
CRC (colorectal cancer) must change to Colorectal cancer (CRC). P for p-value
must be always small and italic. 
3. I request to write the method more clearly. If possible explain Search Strategy,
Inclusion and Exclusion Criteria, Data extraction and quality of assessment and
Statistical analysis separately.
4. You have to use the recent updated version of PRISMA.
5. Reduce the number of tables. You can merge some of the tables or move to
supplementary files.
6. Need to be revise for English grammar, spelling, proper capitalization and
abbreviations.
