Reviewer ’s report  
 
Title: Outcomes of liver –kidney transplantation in patients with primary hyperoxaluria: an  
analysis of the Scientific Registry of Transplant Recipients database  
 
Version: 0 Date: 11 May 2020  
 
Reviewer's report:  
 
The authors compared 20 PH patients underwent SLKT with 181 PH patients underwent CLKT 
based on the SRTR. They showed that patient survival, liver and kidney graft outcomes were not 
significantly different between the two groups. They conclu ded that SLKT seems to be an 
alternative option with strict condition for CLKT. The manuscript is interesting. I have only a 
few minor comments.  
 
Minor comments  
 
#1. Page 7, line 21. "significant" should be "significantly",

#4. Page 8, line 53. "respectively" is not needed.
