医学随访研究设计表及其使用方法
DESIGN TABLES OF MEDICAL FOLLOW-UP STUDIES AND THEIR APPLICATIONS
【摘要】 本文由过去提出的医学随访研究基础方法和应用模型设计出320个常用临床试验方案,制成设计供临床应用.与以往设计相比,其优点是1.便于限定失访水平,2.没有来自信息性终检的偏性,3.便于限定终末终检率在其阈值之下,避免设计错误,保证结果的可靠性,4.设计灵活,无Morgan误差.利用这些表可简化设计过程.附工作实例描述其使用方法.
【Abstract】 Design tables of medical follow-up studies including 320 common projects of clinical trials were made out for clinical applicatications from the basic method and applied models proposed before. By contrast with previous design tables, they have such advantages as 1. convenience for limiting the loss level, 2. no bias from informative censoring, 3. convenience for limiting the administrative censoring rate below its threshold and avoiding wrong designs and unreliable trial results, and 4. high flexibility without the Morgan error. The design procedure is simplified by using these tables. A worked example illustrates the methodology.
