Task: Answer Verification
Input (English): Question: Do scirrhous changes in dysplastic nodules indicate high-grade status?
Answer: This evidence indicated that the scirrhous change in DN was not a specific feature of high-grade DN. We also found that scirrhous DN have two morphological varieties that may represent biologically different processes, that is, pericellular scirrhous type and stellate scirrhous type.
Output (English): no
