RXRG and neoplasm: In the whole cohort and ER-positive sub-cohort, RXRG was associated with features of favourable prognosis, including smaller tumour size (p = 0.036), lower histological grade (p < 0.00001), less pleomorphism (p = 0.042), lower mitotic scores (p < 0.00001), lobular and special tumour types of excellent prognosis (p = 0.016), and lower Nottingham Prognostic Index (p < 0.05; Table 1).
