Reviewer's report:  
 
Kurti et al. demonstrated a nat ionwide description about the therapeutic strategy and outcomes in 
newly diagnosed patients with CD in the biological era in Hungary.  
 
 
 
 
Comments:  
 
1. Only CD patients were included in this study, therefore the title should be changed to "… 
patients with Cro hn's disease…".  
 
 
2. What were the indications for hospitalization and surgery? Are the indications different 
before and after 2009?  
 
 
3. Please provide the p value for "Probability of early steroid exposure was different 
according to the maximum treatment ste p but not according to the year of diagnosis".  
 
 
4. Please provide the overall probability of hospitalization and the proportions according to 
the maximal treatment step in the manuscript.  
 
 
5. What was the definition for "surgery at around the time of diagno sis"?  
 
 
6. The conclusion "IS and biological exposure became more frequent in parallel with 
decreased hospitalization" can not be drawn, because although IS and biological exposure 
became more frequent while the hospitalization rates decreased after vs. befo re 2009, the 
hospitalization rates of patients on anti -TNF were comparable. Please discuss the 
findings.
