n, number of subjects; Q1, first quartile; Q3, third quartile; CI, confidence interval; TG, tinnitus group; T1, first evaluation; T2w/o, second evaluation without prosthesis; T2, second evaluation with prosthesis; T3w/o, third evaluation without prosthesis; T3, third evaluation with prosthesis.
Statistical test used: Wilcoxon.
p-Values obtained in the comparison between time points: T2w/o × T1: 0.022*; T3w/o × T1: 0.002*; T2 × T1: 0.002*; T3 × T1: 0.002*.
