Fig 3. Correlation between serum WBC counts and pleural fluid TCC in the CPPE/empyema and PPE groups.
No apparent associations are seen between serum WBC counts and pleural fluid TCC in the CPPE/empyema group (r = -0.134, p = 0.444) and PPE group (r = -0.172, p = 0.382). CPPE: complicated parapneumonic effusion, PPE: parapneumonic effusion, TCC: total cell count, WBC: white blood cell count.
