N2 - Binary as well as polytomous logistic models have been found useful for estimating odds ratios when the exposure of prime interest assumes unordered multiple levels under matched pair case-control design. In our earlier studies, we have shown the use of a polytomous logistic model for estimating cumulative odds ratios when the exposure of prime interest assumes multiple ordered levels under matched pair case-control design. In this paper, using the above model, we estimate the covariate adjusted cumulative odds ratios, in the case of an ordinal multiple level exposure variable under a pairwise matched case-control retrospective design. An approach, based on asymptotic distributional results, is also described to investigate whether or not the response categories are distinguishable with respect to the cumulative odds ratios after adjusting the effect of covariates. An illustrative example is presented and discussed.
