We performed a 2SMR analysis by Wald ratio method between GIP levels as exposure and CAD (n = 184,305; 60,801 cases, 123,504 controls) and myocardial infarction (n = 171,875; 43,676 cases, 128,199 controls) as outcome variables in CARDIoGRAMplusC4D. The gene discussed is GIP; the disease is myocardial infarction.
