Figure 2: Examples of nuclear morphology of contralateral normal and tumor cells and the distribution of select features. (a) Images of Feulgen-thionin-stained nuclei. (b) Mean of select features for the nuclei pictured in (a). (c) Distribution of select features in contralateral normal (cln), adjacent normal (an), and tumor nuclei. Significance tested using ANOVA of log-10-transformed values with Tukey’s post hoc honestly significant difference test. . ns: not significant.
