Figure 6.

Number of distinct and shared genomic alterations identified in lesions of different histopathology within one biopsy. Each box represents one chromosomal imbalance detected only in the OPL (dark gray), in both OPL and OSCC from the same patient (light gray), or in the OSCC only (white). Patients are divided into those with zero to one copy number change (left) and those with more than five copy number changes (right) in the OPL of their biopsy. Pt. no., patient number; no. chr. imb. in OPLs, number of chromosomal imbalances detected in OPLs.
