Thus the prognostic model was built as follows: Risk score = 2.011 × CREB1 expression + 2.342 × tumor stage –6.740, where the definition was as follows: for CREB1 expression (0 = low expression and 1 = high expression), and for tumor stage (I = 1, II = 2, III = 3 and IV = 4) in each patient. The gene discussed is CREB1; the disease is neoplasm.
