CHR = Chromosome
BP = Basepair (GRCh37 build)
SNP = SNP IDs are from 1000 Genomes Project (Phase I, Version 3)
VAR = Variant allele
REF = Reference allele
ALL.FREQ.VAR = Frequency of variant allele in all GWAS1+2 patients
ALL.RANDOM.BETA = Average change in Consortium lung phenotype for each copy of the variant allele in all GWAS1+2 patients, based on a random effects model
ALL.RANDOM.PVAL = Meta-analysis P value in all GWAS1+2 patients,  based on a random effects model (primary P value)
ALL.FIXED.BETA = Average change in Consortium lung phenotype for each copy of the variant allele in all GWAS1+2 patients, based on a fixed effects model
ALL.FIXED.PVAL = Meta-analysis P value in all GWAS1+2 patients, based on a fixed effects model
FF.FREQ.VAR = Frequency of variant allele in p.Phe508del/p.Phe508del subset
FF.RANDOM.BETA = Average change in Consortium lung phenotype for each copy of the variant allele in p.Phe508del/p.Phe508del subset, based on a random effects model
