Serum concentrations of α1-antichymotrypsin for the three different −15 α1-antichymotrypsin signal peptide genotypes Ala/Ala, Thr/Thr, and Ala/Thr
| α1-antichymotrypsin concentration (g/l) |
Alanine (GG) |
Threonine (AA) | Alanine/threonine (GA) |
| Observed mean (SD) | 0.44 (0.26) | 0.56 (0.26) | 0.52 (0.25) |
| Adjusted mean (95% CI) | 0.45 (0.38 to 0.52) | 0.58 (0.46 to 0.70) | 0.5 (0.42 to 0.57) |
The adjusted mean refers to the level of α1-antichymotrypsin corrected for the inflammatory response in comparison with the level of α1-antitrypsin (see Methods). There was no difference in the levels of α1-antichymotrypsin between the three groups (p=0.184).
