AGR2 and neoplasm: Staining for AGR2 was associated with poorer survival of patients with smaller tumours (T1 tumours n=117; log rank test, P=0.007; Wilcoxon test χ2=7.6, 1 d.f., P=0.006), but not with patients with larger tumours (T⩾2, n=94, log rank test, P=0.6; Wilcoxon test χ2=0.02, 1 d.f., P=0.9).
