  1. SNPs with P < 1 × 10−5 for SBP or DBP dipping (covariate-adjusted systolic or diastolic night-to-day BP ratio using additive genetic model) in the discovery GWAS (GENRES) are shown in order of significance. Explanation for selection of related candidate gene is shown under gene name. Abbreviations: GWAS genome-wide association study, SNP single nucleotide polymorphism, Chr chromosome, EA effect allele, OA other allele, SBP systolic blood pressure, DBP diastolic blood pressure, EAF effect allele frequency, eQTL expression quantitative trait locus
