Scatter plot and forest plot of different metabolite traits’ effect on asthma. Scatter plots and forest plots of MR-derived associations of genetically predicted levels of the ratio of bis-allylic groups to double bonds A, B, the ratio of bis-allylic groups to total fatty acids C, D and the average number of methylene groups in fatty acid chain E–F versus asthma, calculated using the inverse variance weighted (IVW), weighted median, and MR-Egger methods
