This is a study by Vakery at el assessing patient knowledge about cirrhosis and
its association with clinical outcomes, healthcare service use, and healthcare
costs. This was a survey based study and found out that poor disease knowledge
is associated with increase use and total cost of healthcare services, highlighting
importance of educational interventions. 
This is a well written study addressing a less well studied topic in care of
patients with cirrhosis which hopefully open the road for future prospective
interventional studies. 
I have few minor comments/suggestions:
- line 12 abstract: correct length of the study
- can you specify why Indigenous Australians were provided a second
opportunity? How does this affect the response rate?
- I am not clear on the details of CirCare study, does this study involve multiple
visits and nurse education, would this affect your sample? Is this truly a
representative sample of patients with cirrhosis if there is built in extra visits in
CirCare study for these patients?
