TINNITUS
Within-participant changes from baseline in TFI score and tinnitus loudness level from the pilot studyAge at enrollment, sex, and COVID-19 lockdown time (before, during, or after resumption of in-laboratory activities) were controlled for as covariates. Continuous variables were summarized by the means and SDs or 95% CIs. Treatment phase was used as the within-participant factor, and group was used as the between-participant factor to compare differences in the means between treatment groups. In addition to the coefficients reported by the LMER model, between-group changes within a treatment phase were estimated via linear combinations of coefficients from the LMER model.χTwo-sided
