Design outcomes

Primary

MeasureTime frame
Pre-study power calculations to detect cis and trans mQTLs in 13,278 participants showed that we will have 80% power to detect a cis mQTL at a p-val threshold of 1e-8 with rsq is equal to 0.003. We have included a robust and reproducible federated analysis approach. We will develop a github pipeline where collaborators will download a suite of scripts and run the analyses in their cohort. 1.mQTL analyses 2.EWAS analyses 3.Replication 4.MR analysesTimepoint: Total 1 year of the project, consist of 6 months of laboratory execution and 6 months of data analysis
