Following this trimming, we failed to discover a significant reference to LDL, HDL, otherwise TG, and now we note that it trimming techniques led to considerably large CIs spanning Or = 1 for everybody faculties, having stopped advice off impact estimates to possess LDL and you may TGs (S9 Table)
To confirm that our results using lipid genetic associations from MVP were not due to heterogeneity between data sets, we also tested the relationship between lipid traits and BC using a meta-analysis of the 2 major lipid GWASs from MVP and GLGC and from GLGC alone. Overall, single-trait MR analyses with the meta-analysis and GLGC lipid associations produced consistent results to those with MVP alone (S5 Fig). In a reciprocal single-trait MR testing the effect of genetically determined BC risk on each lipid trait, we observed no relationship with HDL- or LDL-cholesterol (S8 Table) but did see a relationship with TGs. However, a Steiger test for directionality confirmed that using BC as the outcome was the correct causal direction for all lipid traits (S7 Table) . We also performed genetic instrument pruning in the same manner as Nowak and colleagues: removing genetic instruments for LDL, HDL, and TGs that were associated with at least one of the 2 other lipid traits (P < 0.001) .
It has been previously seen you to Body mass index and you can ages at the menarche is actually one another genetically correlated and you will epidemiologically in the one another BC [20,43,44] and you may lipid traits [fifteen,41].
