The level of ROR1 overexpression, assessed both by the cut-off value (r > 1 vs r ≤ 1) (Fig. 1a, b and c) and the median one (over and below the median value) (Fig. 2a, b and c) was not associated with overall survival (OS) and this observation was independent of the tumor stage. The gene discussed is ROR1; the disease is neoplasm.
