Table 3 The risk of developing LNN according to the model

From: A model to predict the risk of lethal nasopharyngeal necrosis after re-irradiation with intensity-modulated radiotherapy in nasopharyngeal carcinoma patients

Risk degree No. of total patients Risk of developing LNN Value of logitπ No. of LNN patients
I 56 <25% <−1.099 1
II 90 25%–50% −1.099 to 0 11
III 46 50%–75% 0–1.099 12
IV 12 ≥75% ≥1.099 7
  1. Logitπ was calculated from the model and classified into four degrees according to the corresponding risk of developing LNN
  2. LNN lethal nasopharyngeal necrosis
