Reviewer 2 Report
Dear authors
The prevalence data are ok, but the associative analysis is rather awkward, since only mild and severe cases were compared at rather low numbers of cases (35), but no (healthy) control was included. Thus, it is not asthonishing that nothing meaningful can be deduced from the correlation data. A control group should have been added, maybe this can still be done? The conclusions based on the current correlations should be at least modified or, better, these data should be deleted.
