- ROC receiver operating characteristics, CI confidence interval; SIRS, systemic inflammatory response syndrome
- aClinical scores of each variable present are added. For example, a patient aged ≥65 years, involvement of non-lower limb extremities, SIRS, and no history of liver cirrhosis has a clinical score of: 1 + 1.5 + 0 + 2.5 = 5.0
- bInitial Bacteremia Score of Cellulitis = 1.138 × age ≥65 years + 1.624 × involvement of non-lower extremities + 2.161 × liver cirrhosis + 2.601 × SIRS status
- cRounded Bacteremia Score of Cellulitis = 1 × age ≥65 + 1.5 × involvement of non-lower extremities + 2 × liver cirrhosis + 2.5 × SIRS status
