AFP and neoplasm: As shown in Table 2, univariate logistic regressions revealed that RAE1 expression level, as a categorical dependent variable, was significantly associated with T stage (T2&T3&T4 vs. T1, odds ratio (OR) = 2.03, P < 0.001), pathologic stage (Stage III vs. Stage I, OR = 2.444, P = 0.001), tumor status (with tumor vs. tumor-free, OR = 1.801, P = 0.007), histologic grade (G3 vs. G1, OR = 2.543, P = 0.005), and AFP level (> 400 vs. <  = 400, OR = 2.663, P < 0.001).
