Influence of Tinnitus characteristics, hearing impairments, and psychopathological factors on subjectively perceived tinnitus loudness and on tinnitus-related distress.

In this table, population percentages (%) as well as characteristics (%) of subgroups with low (< = 2) and high (≥8) subjectively perceived tinnitus loudness measured on a numeric rating scale (T-NRS) from 0 (tinnitus audible only during silence) to 10 (louder than all external sounds), and mild (MTQ score≤7) and severe (MTQ score≥19) tinnitus-related distress are shown. Absolute numbers deviate because of missing data in single items. Percentages for type of tinnitus onset and tinnitus localization exceed 100%, because participants with two distinguishable tinnitus tones coded multiple categories. Variables with values marked in bold because of odds ratios (OR) of 2 and above or 0.5 or below were included in the regression analysis.
CI – confidence interval of OR, MTQ – short version of the tinnitus questionnaire, N – number.
