TSSA (p < 0.05), SOD (p < 0.05), XO (p < 0.05), and MDA (p < 0.01) levels were found to be significantly higher in the experimental OME group than in the control group, although there were no significant between-group differences in NSSA and CAT activities (p > 0.05 each) [47]. Here, XDH is linked to otitis media with effusion.
