目的 利用两样本孟德尔随机化研究茶摄人量与结宜肠癌发病的因果关系,, 方法 利用IEU OPEN GWAS公共 数据库中的结直肠癌全基因组关联分析数据(GWAS ID:icu-b-496 5)和茶摄入量全基因组关联分析数据(GWAS ID:nkb-b-606 6),汇总两个数据集, 筛选与茶摄入量密切相关且独立的单核昔酸多态性(SNPs)作为工具变量 (IVs), 通过采用两样本孟德尔随机化中的MR - Egger、逆方差加权(LVW)、加权中位数法(Weighted Median)、简单模 型(Simple Mode)和加权模型(Weighted Mode)五种方法进行茶摄入量与结直肠癌发病的因果分析的判断, 采用OR以 及95% CI判断茶摄入量与结宜肠癌发病是否存在因果关系, 利用MR - PRESSO进行离群值检验, 采用IVW(Cochran Q检验)以及MR - Egger(Rik'ker Q检验)进行异质性分析, 采用Egger - intercept进行多效性检验,通过留一法进行敏 感性分析, 采用漏斗图分析是否存在潜在偏倚"结果 最终纳入39个SNPs, MR - PRESS0未发现离群SNPs,P = 0. 237 >0.05;在因果关系的判定上:IVW(OR = 0. 996,95% CZ:O. 990 ~ 1.002, P = 0. 293), MR - Egger (OR =0. 992, 95%Cl:0. 977 -1.007,P = 0. 293) ,Weighted Median(ORO. 997,95%CZ:O. 987 ~ 1.007,P = 0.479) ,Simple Mode(OR = 0. 996,95%CZ:O. 976 ~ 1.017=0. 724), Weighted Mode(07? = 0. 996,95% Q:0. 985 〜!. 007,P = 0. 473),上述结果显 示:茶摄入量与结直肠癌发病无因果关系, 在异质性检测中Cochran Q检验中P=0. 181 > 0. 05, R iickcr Q检验中P = 0. 167 >0. 05,无显著异质性,Egger - intercept进行多效性检验P =0.489 > 0. 05未见多效性, 留一法逐个剔除,未见明 显影响结果的SNPs,漏斗图基本对称, 显示主结果可靠"结论 茶摄入量与结直肠癌发病无因果关系,.
