- 遗传流行病学遗传流行病学
背景情况:
- 观察性研究表明,胃食道逆流性疾病 (GERD) 和心房动 (AF) 之间存在联系.
- 原因方向和潜在的混因素 (肥胖,睡眠呼吸障碍) 仍然不清楚.
- 双向门德尔随机化 (MR) 用于调查因果关系,减轻混和反向因果关系.
研究的目的:

Gastroesophageal Reflux Disease I: Meaning and Pathophysiology
304
Gastroesophageal Reflux Disease (GERD) involves the recurrent backflow of the stomach or duodenal contents into the esophagus, leading to troublesome symptoms and potential esophageal mucosal damage. Although GERD is often referred to as a disease, it is more accurately described as a syndrome, as it encompasses a range of symptoms and complications rather than a singular pathological entity, impacting a large number of individuals as the most prevalent upper gastrointestinal problem. Roughly...

Genome-wide Association Studies-GWAS
13.3K
Genome-wide association studies or GWAS are used to identify whether common SNPs are associated with certain diseases. Suppose specific SNPs are more frequently observed in individuals with a particular disease than those without the disease. In that case, those SNPs are said to be associated with the disease. Chi-square analysis is performed to check the probability of the allele likely to be associated with the disease.
