Overview
Brief Summary
This study aims to investigate the causal relationship between rheumatoid arthritis and periodontitis using Mendelian randomization. Data will be sourced from genome-wide association studies (GWAS) to explore genetic associations and assess potential risk factors in an East Asian population.
Detailed Description
The purpose of this study is to explore the causal association between rheumatoid arthritis (RA) and periodontitis using Mendelian randomization (MR). RA and periodontitis share similar inflammatory pathways and immune responses, but their causal relationship remains unclear. This study will utilize genome-wide association studies (GWAS) data from an East Asian population to identify single nucleotide polymorphisms (SNPs) associated with RA and assess their potential impact on the risk of developing periodontitis. Statistical methods such as inverse-variance weighting, MR-Egger regression, and weighted median analysis will be employed to analyze the data. The findings may provide insights into the shared genetic basis and causal relationships between these two conditions, offering potential targets for preventive strategies.

Causal Association Between Rheumatoid Arthritis and Periodontitis
Time Frame: Data collected from 2023 to 2024.
This study uses Mendelian randomization to evaluate the causal relationship between rheumatoid arthritis (RA) and periodontitis in the East Asian population. The analysis utilizes genome-wide association study (GWAS) data, employing inverse variance weighting (IVW), weighted median, and MR-Egger regression methods to assess the genetic relationship and the risk contribution of RA to the development of periodontitis.
Secondary Outcomes
- Analysis of Genetic Pleiotropy and Confounders(2023 to 2024)
