  1. For this prediction model the formula eβ0+c+ β1X1+…βkXk / 1 + e β0+c+ β1X1+…βkXk was used, whereas β was deduced from the multivariate regression analysis as shown in Table 5. 0  variable absent, 1  variable present A  Colonization with E. faecium 30 days prior to blood culture B  Neutropenia and abdominal focus (diarrhea or abdominal pain) C  Age over 58 years D  Days of admission prior to blood culture more than 14 days E  CRP >125 mg/L.
