Comparing results for associations of sleep traits on risk of Alzheimer’s disease (AD) when using the International Genomics of Alzheimer’s Project (IGAP) genome-wide association study (GWAS) alone (n = 17 008 AD cases and 37 154 controls; IGAP) vs the GWAS meta-analysis of IGAP, the AD working group of the Psychiatric Genomics Consortium and the AD Sequencing Project (n = 24 087 cases and 55 058 controls: META data). Note that the MR Egger estimate for effect of accelerometer-measured sleep fragmentation using IGAP data was not plotted due to imprecision. MR, Mendelian randomization; AM, accelerometer-measured; SR, self-report
