Fig. 1From: Gut microbial features may influence antiviral IgG levels after vaccination against viral respiratory infectious diseases: the evidence from two-sample bidirectional mendelian randomizationThe workflow diagram of this study. Plot A lists the detailed steps of two-sample MR in this study mentioned in the method, and Plot B shows how to do two-sample MR bidirectionally. X represents one of 412 microbial features, while Y represents one of 4 IgG levelsBack to article page
