Statistical Method for Analysis of Responses in Control Critical Trials with Three Outcomes

Oyeka I. C. A. and Nwankwo Chike H.

This paper proposes a statistical method for the analysis of multiple responses or outcome data in case control studies including situations in which the observations are either continuous or frequency data. Test statistics are proposed for assessing the statistical significance of differences between case-control response score. The proposed methods are illustrated with some sample data. When there only three possible response options in which the proposed method and the Stuart- Maxwell test can be equally used to analyse the data, the proposed test statistic is show to be at least as powerful as the Stuart-Maxwell test statistic.
