Causal relationship between key genes and metabolic dysfunction‐associated fatty liver disease risk mediated by immune cells: A Mendelian randomization and mediation analysis

Non-invasive diagnostics for metabolic dysfunction-associated fatty liver disease (MAFLD) remain challenging. We aimed to identify novel key genes as non-invasive biomarkers for MAFLD, elucidate causal relationships between biomarkers and MAFLD and determine the role of immune cells as potential mediators.
