nested case–control designcohort studyThe case–cohort design includes a randomly sampled subcohort that is selected without regard to disease status or disease event times from the entire cohort, plus those cohort members who develop disease (cases) and who are not members of the subcohort. ...
病例-队列研究(case-cohort study) 又称病例参比式研究(case-base reference study),也是一种队列研究与病例对照研究结合的设计形式。队列研究开始时,在队列中按一定比例随机抽样选出一个有代表性的样本作为对照组,观察结束时,队列中出现的所研究疾病的全部病例作为病例组,与上述随机对照组进行比较。在流行病学研究中...

NCCS设计和病例队列研究设计(case cohort design)就能使之梦想成真。在膳食调查中,个人饮食可以根据对不同时期摄入食物的详细膳食调查来评估。运用计算机分析这些记录编码和描述非常吃力而且代价很高。如果应用NCCS方法,只需对随访过程中发病的病例,以及为每一例病人所选取的对照进行编码,可以省去大量的工作。当对生物学...

3、病例交叉研究（case-crossoverdesign)：比较相同研究对象在急性事件发生前一段时间的暴露情况与未发生事件的某段时间内的暴露情况，如果暴露与少见事件（疾病）有关，则在事件发生前的这一段时间内的暴露频率应该高于更早时间内的暴露频率。4、单纯病例研究（caseonlystudy）；（病例系列研究caseseriesstudy）；（...
Odds ratio and relative risk estimation procedures are presented for such a `case-cohort' design. A small simulation study compares case-cohort relative risk estimation procedures to full-cohort and synthetic case-control analyses. Relevance to epidemiologic cohort studies and disease prevention trials ...

The case-cohort study design is a useful modification of the case-control design, which allows direct estimation of the risk ratio without the rare-disease assumption. While several risk ratio estimation procedures have been proposed under large-strata settings, only the Mantel-Haenszel point estimato...
