[Retracted] Mendelian Randomization Study of Causal Relationship between Omega-3 Fatty Acids and Risk of Lung Cancer

Figure 1

Forest plot of single-nucleotide polymorphisms (SNPs) associated with omega-3 fatty acids and risk of lung cancer. Each black point indicates the log odds ratio (OR) for lung cancer per standard deviation (SD) increase in omega-3 fatty acids, generated utilizing each omega-3 fatty acids-associated SNP as an instrument. The horizontal line denotes 95% confidence intervals of the estimates. The red point shows the combined causal estimates utilizing all SNPs as an instrument based on MR-Egger and inverse-variance weighted (IVW) approaches.
