Fig. 2From: The association of delta neutrophil index with the prognosis of acute exacerbation of chronic obstructive pulmonary diseaseFig. 2 shows mean DNI levels among four groups. Mean DNI values are 9.5 ± 9.2, 5.0 ± 4.6, 2.9 ± 2.6 and 1.7 ± 2.6%, respectively. It is significantly higher in AECOPD with CAP (readmitted ≤30 d) than without CAP. AECOPD = acute exacerbation of chronic obstructive pulmonary disease; CAP = community-acquired pneumonia; DNI = delta neutrophil index; d = daysBack to article page
