Reviewer’s report:  
 
The aim of the article is interesting and the study was well prepared.  
 
However, some aspects must be amended:  
 
(1) english language must be improved  
 
(2) Background  
 
- the aim was to assess eMayo or PanMayo score? Must be clarified.  
 
- there  should be a brief description of riley score in the introduction, as you are using it in 
the next section without any introduction.  
 
- there should be a reference regarding the association of disease extent and the severity of 
UC.  
 
(3) Patients and Methods  
 
- "Inflammatory Constant" definition shall be better clarified. Why should you include it, if 
eMayo score already characterizes the disease severity? It is not well justified...  
 
- time of follow -up shall be included.  
 
(4) Results  
 
- In 3.1. - what is the dif ference between proctosigmoiditis and left -side colitis?  
 
(5) Discussion  
 
- a reference regarding the sentence "endoscopic score indicate the severity of 
inflammation, ..., for the optimisation of the therapy" must be added.  
 
- line 37, "it should be noted that disease location..." and extension too.  
 
- most importantly, a real advantage of panmayo score versus the current scores (mayo 
score and uceis) must be better developed. From what it is exposed, it is not perceptible. 
As a matte r of fact, UCEIS and Mayo score already assess disease activity with less 
parameters than panMayo score... This is a major point to be addressed by the authors 
before considering this paper for publication.
