Fig. 1From: Propensity-matched analysis of three different chemotherapy sequences in patients with locoregionally advanced nasopharyngeal carcinoma treated using intensity-modulated radiotherapyKaplan–Meier survival curves. Disease–free survival (a), overall survival (b), distant metastasis–free survival (c) and locoregional relapse–free survival (d) for the CCRT group, IC plus RT group and IC plus CCRT group. P-values were calculated using the unadjusted log–rank test. IC, induction chemotherapy; RT, radiotherapy; CCRT, concurrent chemoradiotherapyBack to article page
