However, the causal connection between FAs, gut microbiota, and ICP has not yet been confirmed. To investigate the associations of FAs, gut bacteria, and ICP, a Mendelian randomization (MR) analysis with two samples was performed to identify the potential causal relationships between FAs and ICP. The potential mediating role of gut bacteria in FAs and ICP was analyzed by a two\u2010step MR analysis. False discovery rate (FDR) correction was conducted to correct the bias of multiple tests. MR analysis revealed that higher omega\u20106 FAs\/total FAs (odds ratio [OR]\u2009=\u20092.563, 95% confidence interval [CI]\u2009=\u20091.362\u20134.824, FDR <jats:italic>p<\/jats:italic>\u2009=\u20090.016), linoleic acids\/total FAs (OR\u2009=\u20093.812, 95%CI\u2009=\u20091.966\u20137.388, FDR <jats:italic>p<\/jats:italic>\u2009=\u20090.001), and average number of methylene groups (OR\u2009=\u20091.968, 95%CI\u2009=\u20091.390\u20132.785, FDR <jats:italic>p<\/jats:italic>\u2009=\u20090.001) are potential risk factors for ICP. However, omega\u20103 FAs (OR\u2009=\u20090.587, 95%CI\u2009=\u20090.394\u20130.874, FDR <jats:italic>p<\/jats:italic>\u2009=\u20090.031) and the average number of double bonds in an FA chain (OR\u2009=\u20090.575, 95%CI\u2009=\u20090.435\u20130.759, FDR <jats:italic>p<\/jats:italic>\u2009=\u20090.001) could reduce the risk of ICP.
