General tinnitus efficacy at discharge and analysis of correlated factors
According to the efficacy evaluation of tinnitus, we divided the 161 patients into four groups at discharge: 24 cases were cured (14.9%), 11 cases were markedly effective (6.8%), 75 cases were effective (46.6%), and the remaining 51 cases were invalid (31.7%). The total effective rate was 68.3%. A T -test and the chi-square test were used for statistical analysis of related factors (Table 2). The analysis showed that the initial level of tinnitus at admission, hearing recovery, and laterality were related with the outcome of tinnitus at discharge (P < 0.1). Then, binary logistic regression analysis was applied to explore the independent related factors of tinnitus efficacy at discharge. Here, we incorporated statistically remarkable factors including the initial level of tinnitus at admission, hearing recovery, laterality, and SSNHL grades, which were not statistically moderate but were clinically remarkable, into a multivariate analysis. The analysis showed that the initial level of tinnitus was an independent relevant factor for the efficacy of tinnitus at discharge (P = 0.000).
