MAF, minor allele frequency (major allele ‘C’, minor allele ‘A’); β, Regression coefficient; OR, Odds ratio; na, not applicable. The β/OR and P-values were generated by using linear regression model (for sleep duration) and logistic regression model (for short sleepers vs. midrange sleepers as well as long sleepers vs. midrange sleepers).
