Reviewer's report: 
General 
I read this paper and the somewhat divergent reviews. 
I agree with reviewer 1 that the issue of ascertainment bias must be addressed. 
I would give the authors an opportunity to address this and also the 
following issues: 1. It is poorly written and needs to be carefully re-written. 2. The nature of the control population needs to be described in much 
more 
detail. 
------------------------------------------------------------------------------- 
Major Compulsory Revisions (that the author must respond to before a decision on publication can be 
reached) 
------------------------------------------------------------------------------- 
Minor Essential Revisions (such as missing labels on figures, or the wrong use of a term, which the author can be trusted to correct) 
------------------------------------------------------------------------------- 
Discretionary Revisions (which the author can choose to ignore)
