From: Procalcitonin levels and bacterial aetiology among COPD patients admitted to the ICU with severe pneumonia: a prospective cohort study

Figure 1

Distribution of the highest procalcitonin level measurements (PCTmax) and microorganism findings in chronic obstructive pulmonary disease (COPD) patients with pneumonia. Also shown is the probability of bacterial infection according to procalcitonin (PCT) levels, as previously reported by Christ-Crain (11). * Procalcitonin (PCT) levels were not assessed in 2 patients. ** One patient receiving antibiotic in 24 h prior ICU was not assessed for PCT levels.
