It is evident that statistical analysis of such pathology data will continue to be essential for the process of human risk estimation. Much of this data is tabulated (converted to numbers) on the basis of classification schemes selec

One of the key elements in interpretation of these studies is the histopathologic evaluation of tissues from the test animals.

One way of overcoming the difficulty introduced by varied nomenclature and diagnostic criteria is to have the primary pathologist or several pathologists re-evaluate histological sections of the tissue in question from a defined series of historical control groups.
