Furthermore, a composite score (CIBLE score) that includes age, CRP, temperature, chronic obstructive pulmonary disease (COPD) and eosinophils/granulocytes count ratio, was found to predict bacterial infection when > 87, with a 72% sensitivity and a 77% specificity (190 patients, 73.5 (18.2) y/o) [18]. Here, CRP is linked to bacterial infectious disease.
