Estimated effects of
genotypes on inflammatory cells in bronchial biopsies of COPD patients. Number of macrophages according to rs4781699 genotype. N = number of individuals. Data are presented as natural logarithm of each type of cells in bronchial biopsies. Different numbers for the SNP genotypes are due to missing data on genotype or inflammatory cells. Squares represent the regression coefficient (B) and vertical bars the 95% confidence interval (CI). Wild type was set to zero as the reference category. The analyses are adjusted for age, gender and packyears.
