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).
