Modulation of the risk for death after 28 days in relation to the underlying infection and the number of comorbidities. Each line represents the odds ratios and confidence intervals (CI) for death in the presence of one or at least two comorbidities, as defined for each infection in Table 2. P values represent comparisons with patients without any comorbidity. The p-values of comparisons between odds ratio for one moborditiy and for at least two comorbidities are: *0.00002; ^#0.0029. **could not be calculated because one value was zero
