TNF and mucositis: A higher frequency of the unmethylated profile(48%) of TNF-α was found in oncopediatric patients whorecovered from mucositis at the time of sample collection (p = 0.002; Fisher’sexact test), than in healthy patients (20%) (p = 0.047;Dwass-Steel-Critchlow-Fligner multiple comparisons test) and oncopediatricpatients with mucositis (6%) (p = 0.018; Dwass-Steel-Critchlow-Fligner multiplecomparisons test) and without mucositis (7%) (p = 0.032;Dwass-Steel-Critchlow-Fligner multiple comparisons test) (Figure 2).
