Association results between the SNPs in the PGF gene and the protein levels according to the best fitting models for the Cilento and Denmark samples.

Association for the five PGF SNPs and the protein levels is reported for Cilento; only the SNPs associated in Cilento were tested in Denmark. Statistical associations are all adjusted for age, sex, menstruation, smoking, sex/smoking interaction (only for Cilento) and “disease status”.*Minor allele referred to the reverse strand according to PGF position.†The CEU sample was chosen as reference population of the HapMap data.‡Test corrected for relatedness between individuals. Multiple testing p-value threshold = 0.0127. Significant results are given in bold.§P-value from meta-analysis (see Material and Methods section for details).
