Relationship between demographic and clinical variables with mono-infection and co-infection is shown for both GENDRES and UK cohort.

The correlation was analysed using simple logistic regression. Data are presented as OR (95% confidence interval) and P-value. The characteristics of the two cohorts analyzed were compared and when P-value results were significant when different: the GENDRES cohort and the UK cohort. P-value results from the comparison between both cohorts. A P-value < 0.005 was considered significant.
