95%CI 为 1.001~1.005,P=0.005,提示抑郁会导致 学意义(P < 0.05),优选MR⁃Egger同样提示抑郁可导
NERD 的风险升高,抑郁人群中患有NERD的风险是 致NERD风险升高,抑郁人群中患有NERD的风险是
正常人的1.003倍。MR⁃Egger、Weightedmedian、Simple 正常人的1.019倍。敏感性分析:留一法显示所有SNP

Effect of depression on GERD Effect of depression on RE Effect of depression on NERD
A:Causal effect of depression on GERD and its subtypes. P < 0.05 indicates a causal relationship,and the OR value represents the strength of the
association(forest plot). B:The impact of depression on GERD,with each point representing the robustness of the causal effect evaluated by the IVW method
after removing a single SNP(leave⁃one⁃out analysis). C:The impact of depression on RE(leave⁃one⁃out analysis). D:The impact of depression on
NERD(leave⁃one⁃out analysis).
