Venn Diagram from Scientific Research

Venn diagram of suggestive causal results using IVs inside, outside MHC region or all IVs. The Venn diagram showed the number of traits that were suggestively casually associated ( P < 0.05 in at least three Mendelian randomization methods) with anti-VZV IgG levels using instrumental variables inside MHC region (IV mhc ) (green circle), outside MHC region (IV no.mhc ) (blue circle) and combined IVs (IV full ) (yellow circle). Numbers in the overlapping region represent the causal traits identified by both or all IV sets
