Clinical discriminator for scrapie status based on classification and regression tree analysis. The number in or above each bar is the number of animals with a positive (red font and bar) and negative (black font and bar) scrapie status based on examination of brain tissue by all confirmatory tests. N is the number of animals remaining in each node (blue box = intermediary node, yellow box = final node). The term “Negative” of “Positive” in each node corresponds to the clinical scrapie status.
