Box plots showing procalcitonin (PCT) levels, C-reactive protein (CRP) levels, and white blood cell (WBC) counts according to pneumonia severity determined by the pneumonia severity index of elderly (≥75 years old) patients with Streptcoccus pneumoniae pneumonia occurring outside the hospital setting. The box plots show 25th, 50th, and 75th percentiles, and outliers. **: p < 0.01
