Figure 1From: Detecting disease-associated genes with confounding variable adjustment and the impact on genomic meta-analysis: With application to major depressive disorderThree correlation structures of interest among disease variables X, gene expression variable Y and putative confounding covariates Z that are used in the simulation. Scenario I: gene expression depends on both disease state and covariates. Scenario II: gene expression depends only on disease state. Scenario III: gene expression depends on disease state directly and depends on covariates indirectly through disease state.Back to article page
