Abstract excerpt
INTRODUCTION: The causal relevance of circulating plasma protein-to-protein ratios (PPRs) in Rheumatoid Arthritis (RA) remains unclear. We employed Mendelian Randomization (MR) to investigate this relationship. METHODS: This study utilized summary data of ratio quantitative trait loci (rQTLs) for 2,821 circulating PPRs from the GWAS Catalog and two RA-related GWAS datasets (FinnGen and GWAS Catalog). Causal...
