Fig. 4From: The potential value of ultrasound in predicting local refractory/relapse events in primary thyroid lymphoma patientsEvent-free survival curves of patients with type A of thyroid gland enlargement or type B/C of thyroid gland enlargement (A), diffuse or non-diffuse ultrasound types (B), MALT or other pathological subtypes (C), IPI low-risk or IPI medium-high risk (D), rich or few-medium blood flow (E), or signs of suspicious cervical lymph node (LN) metastasis (F). The differences between two curves in panel A and B were significant.
