FIG. 2.

A) Mean Tinnitus Handicap Inventory (THI) scores for the pre-operative, 6-month post-operative, 12-month post-operative, and most recent follow-up time points. Error bars represent one standard deviation. Asterisks note adjusted significant differences: ****p<0.0001. B) Scatter plot of pre-operative THI vs post-operative THI for each user that completed these questionnaires. Each dot represents the pre- and post-implantation scores for an individual patient. The minimal clinically important difference of ΔTHI = 7 is demarcated by dashed lines. Points below the lines demonstrate improvement in THI, while points within the dashed lines signify no MCID in THI.
