| The values are number of ducts staining positively/total number of ducts involved by DCIS. | |||||||||
| *The difference in the proportion of ducts staining positively was significant at p = 0.02 or better using Fisher’s exact test. Other results were not significant at the 0.25 level. | |||||||||
