RORB and neuroblastoma: Notably, in 498 (GSE62564), 649 (GSE45547), and 283 (GSE85047) NB cases, RORB expression was reduced in tissues with death (P = 9.1 × 10−5, P = 2.0 × 10−2, P = 3.8 × 10−8) or stage 4 (P = 7.5 × 10−6, P = 1.2 × 10−11, P = 3.1 × 10−7, Figure 1B; Figure S1A, Supporting Information), which was associated with poor overall (P = 8.2 × 10−7, P = 1.2 × 10−10, P = 4.5 × 10−9) or event‐free (P = 1.6 × 10−5, P = 3.2 × 10−6, P = 1.0 × 10−7) survival of patients (Figure 1C; Figure S1B, Supporting Information).
