From: Differential expression of C-Reactive protein and Serum amyloid A in different cell types in the lung tissue of chronic obstructive pulmonary disease patients

  Controls (n = 34) COPD (n = 40) P value*
Males (n) 26 (76.5) 37 (92.5) NS
Age (years) 63.1 (10.7) 66.2 (7.6) NS
Tobacco history (pack-years) 48.8 (101.3) 51.5 (27.7) NS
Comorbidities (Charlson index) 2.6 (1.6) 3.9 (1.3) <0.001
BMI (kg/m2) 26.5 (4.5) 25.8 (7.07) NS
FVC (%) 90.6 (17.1) 93.1 (17.9) NS
FEV1 (%) 86.2 (16.5) 72.2 (16.4) 0.001
FEV1/FVC (%) 75.6 (6.3) 61.2 (8.8) < 0.001
  1. The data are expressed as absolute (relative) frequencies or means (standard deviations), as appropriate. *p values were calculated using Chi-square or Mann–Whitney tests, as appropriate.
  2. BMI: body mass index. FVC: forced vital capacity. FEV1: forced expiratory volume in one second. NS: not significant.
