Mean differences in CRP and SAA values measured by the two analytical assays (nepholometry and ELISA) in COPD patients and healthy controls
| Entire cohort (n = 133) | COPD (n = 88) | Controls (n = 45) | p value* | |
|---|---|---|---|---|
| CRP (mg/L) | 2.7 (9.4) | 3.9 (11.1) | 0.4 (4.1) | 0.009 |
| SAA (mg/L) | 0.31 (14.3) | 1.2 (17.2) | -1.4 (5.9) | NS |
NS, not significant
* p value calculated by unpaired Student's t test.
