In some medical researches such as ophthalmological, orthopaedic and otolaryngologic studies, it is often of interest to compare multiple groups with a control using data collected from paired organs of patients. The major difficulty in performing the data analysis is to adjust the multiplicity between the comparison of multiple groups, and the correlation within the same patient's paired organs. In this article, we construct asymptotic (SCIs) for many-to-one comparisons of proportion differences adjusting for multiplicity and the correlation. The coverage probabilities and widths of the proposed CIs are evaluated by Monte Carlo simulation studies. The methods are illustrated by a real data example.
在一些医学研究中,如眼科、骨科和耳鼻喉科研究,使用从患者配对器官收集的数据将多个组与一个对照组进行比较通常很有意义。进行数据分析的主要困难在于调整多个组比较之间的多重性,以及同一患者配对器官内的相关性。在本文中,我们构建了用于比例差异多对一比较的渐近同时置信区间(SCIs),对多重性和相关性进行了调整。通过蒙特卡罗模拟研究评估了所提出置信区间的覆盖概率和宽度。通过一个实际数据示例对这些方法进行了说明。
