The MR analysis showed PWY0.1298..superpathway.of.pyrimidine. deoxyribonucleosides.degradation was highly associated with Guillain–barre syndrome. The r-MR analysis showed Guillain–barre syndrome was not associated with PWY0.1298..superpathway.of. pyrimidine.deoxyribonucleosides.degradation. CI: Confidence Interval; MR: Mendelian randomization; r-MR: reverse mendelian randomization: OR: odds ratio; snp: single nucleotide polymorphism.
