These summary statistics files (summary_stat_gwas_singleitemchronotype.txt.gz,summary_stat_gwas_smeqbinary.txt.gz and 
summary_stat_gwas_smeqcont.txt.gz) are associated with the manuscript "Genetic associations of chronotype in the Finnish general population" (doi: 10.1177/0748730420935328)

Phenotype: self-reported chronotype (a shortened six-item (items 4, 7, 9, 15, 17 and 19) version of Horne and Östberg’s (1976) questionnaire and a single self-evaluation question on chronotype)
Data: The study included Caucasian, Finnish participants from the population-based cross-sectional FINRISK 2007 and 2012 Studies covering age groups between 25 and 74 years 
Sample size: n = 8433
Covariates: age, sex, five principal components, genotyping batch 

Column descriptions
CHR = chromosome
POS = position (GRCh37 - hg19)
ID = SNP rsid 
A1 = effect allele 
A2 = non-effect allele 
P = p-value for the association between SNP and chronotype
BETA/OR = effect size of A1 on chronotype (OR for evening chronotype)
n= sample size for each SNP
EAF(A1)= frequency of the effect allele
