| Drug target | |||||
| Lipid lowering target10 | One for HMGCR, two for LDLR, one for NPC1L1, two for PCSK9 | 10 mg/dL LDL cholesterol | 80 959 to 295 826 individuals of European descent | 0 | Age, sex, study sample, and five principal components |

Sample overlap was calculated by the sample size of the outcome (n=32 974) divided by the sample size of the exposure whose data sources included UK Biobank. ACEi=angiotensin converting enzyme inhibitor; BMI=body mass index; CCBs=calcium channel blockers; HDL=high density lipoprotein; LDL=low density lipoprotein; SD=standard deviation.
