Fig. 1From: Association between sleep duration and metabolic syndrome: linear and nonlinear Mendelian randomization analysesLinear Mendelian randomization estimates for the associations between genetically predicted sleep duration with MetS and its five components. CI: Confidence interval; MetS: Metabolic syndrome; OR: Odds ratios. The two-stage least squares regression models for each outcome were adjusted by age, sex, assessment center, top 10 genetic principal components and genotyping array. Statistical significance was defined as Bonferroni-corrected threshold of P < 0.008 (0.05/6)Back to article page
