Of the patients, 17 were nonsmokers and 14 were smokers. No significant relationship was found between smoking status and relapse and dysplasia. In contrast, a significant relationship between the Krouse stage and dysplasia (\n                      <jats:italic toggle=\"yes\">P<\/jats:italic>\n                      = 0.005) was observed.
