Fig. 2From: A novel dosimetric metrics-based risk model to predict local recurrence in nasopharyngeal carcinoma patients treated with intensity-modulated radiation therapyUnivariate and multivariate analysis of dosimetric metrics. a Eight dosimetric metrics were significantly correlated with LRFS derived from the univariate analysis using a cox regression model; b Two dosimetric metrics were statistically correlated with LRFS derived from the Cox regression analysis using a stepwise method with likelihood-ratio.
