Modulation of the risk for sepsis in relation to the underlying infection and the number of comorbidities. Each line represents the odds ratios and confidence intervals (CI) for sepsis in the presence of one or at least two comorbidities, as defined for each infection in Table 1. P values represent comparisons with patients without any comorbidity. The p-values of comparisons between odds ratio for one comoborditiy and for at least two comorbidities are: *0.00002; **0.033; ^#0.0018
