  1. DLBCL, diffuse large B-cell lymphoma; FL, follicular lymphoma. Each CGH alteration in subsequent relapses from the same case was counted once, in tumors of the same diagnosis (FL/DLBCL). For mean number of CGH alterations, all tumors were included. Bold style indicates a statistically significant P-value, NS indicates a not statistically significant P-value.
