CRP Causality Refined Through Heritable Confounder Adjustment
Key Highlights
Medicine · Public Health · Genetic Epidemiology
A new study applied multivariable Mendelian randomization (MVMR) with a computational pipeline to systematically adjust for heritable confounders in estimating the causal effects of C-reactive protein (CRP) on 16 health outcomes. Researchers found that after adjusting for such confounders, previously observed causal effects of CRP on coronary artery disease, LDL cholesterol, and type 2 diabetes were no longer significant, while effects on HDL cholesterol, HbA1c, rheumatoid arthritis, and schizophrenia remained. For a nurse and psychologist focused on chronic disease prevention, this work provides more robust causal evidence on the role of inflammation in metabolic and autoimmune conditions, informing which pathways may be the most promising targets for behavioral and clinical interventions.
