  1. M, major allele; m, minor allele; MAF, minor allele frequency; pFDR, P-value adjusted for false discovery rate.
  2. aP-values are based on linear regression analysis of sleep duration adjusted for age, sex, area, occupation, and principal components (PCs, PC1 to PC10). An additive genetic model was used in the present study.
