Exploratory experiment designed to discover new patterns targeting C1Q in Human genetic association data. Primary outcome: Causal association between C1Q and ischemic stroke risk
This genetic epidemiological study employed bidirectional Mendelian randomization (MR) analysis to investigate the causal relationship between C1Q levels and ischemic stroke risk, specifically focusing on large artery atherosclerosis subtype. The analysis used genetic variants associated with C1Q as instrumental variables to assess causality while avoiding confounding factors that typically plague observational studies. Inverse variance weighting (IVW) was employed as the primary statistical method. The bidirectional approach allowed assessment of causality in both directions - whether C1Q influences stroke risk and whether stroke risk influences C1Q levels. This approach leverages the random assortment of genetic variants to provide evidence for causal relationships.
