Review for 10.1186/s12876-021-01802-9 (2021)

Reviewer’s report
Title: 
Schistosoma mansoni-related periportal fibrosis; can we use APRI and
PSDR levels in the real-time selection of patients for targeted endoscopy in a
resource-limited setting? A case-control study
Version: 
2 
Date: 
14 Feb 2021
Reviewer's report:
As a diagnostic test it would be better to include a validation population to
confirm the diagnostic value of APRI and PSDR.
The limitation of the lack of Computed Tomography of the included patients
should be added into the discussion.
