As detailed in Table The 3‐state Markov model is shown in Figure Cost‐effectiveness analysis.Abbreviations: ICER, incremental cost‐effectiveness ratio; NTF, nasogastric tube feeding; ONS, oral nutrition support; PEG, percutaneous endoscopic gastrostomy; QALY, quality‐adjusted life‐year.In one‐way analysis, the ICER was sensitive to the treatment cost of radiotherapy, routine follow‐up, and nutrition support cost and was also sensitive to the probability of mortality, relapse, and utility after treatment. The model variables in the order of their influence on the ICER were presented in Figure
