Fig. 1From: Identification of genetic loci jointly influencing COVID-19 and coronary heart diseasesThe study pipeline to investigate putative COVID-19-mediated causal pathways to CHD. * X and Y in blue circles are nonspecific designations for either COVID-19 or CHD, depending on previous results from bidirectional Mendelian randomization. G in green circles are putative causal SNPs (either of vertical pleiotropy or horizontal pleiotropy) to be identifiedBack to article page
