Interactive dot diagram of (a) fresh frozen biopsy and (b) FFPE samples according to the multiple logistic regression equation. On the basis of the previously published transcript set, a multiple logistic regression equation was applied to the present study’s results. The results can be visualized on interactive dotblots, normal and tumor groups are displayed as dots in two separate groups and the horizontal line indicates the cut off point with the best sensitivity and specificity results. The sensitivity and specificity values are calculated by the algorithm, that can be seen beside the dotblots
