NCCS设计和病例队列研究设计(casecohortdesign)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...

Under the nested case-control design, the asymptotic distribution of\(\hat{\varvec{\beta }}\)is more difficult to derive because the NCC sampling scheme is a dynamic process. The probability of being selected as a control is neither a constant not independent. Thus, we consider the idea of...

A population based nested case-control study design was used. Data were taken from the UK QResearch primary care database consisting of 7?267?673 patients. Cases were adult patients with a first ever record of venous thromboembolism between 1 January 1996 and 1 July 2007. For each case, up...
