Tinnitus-related distress (MTQ)	OR [95% CI]	Subjective tinnitus loudness (T-NRS)	OR [95% CI]
Depressivity (PHQ-9)****	19.67 [5.29–73.12]	Permanent awareness of tinnitus****	24.04 [9.25–62.45]
Anxiety (GAD-7)*	14.19 [1.52–132.42]	Binaural tinnitus localization***	4.77 [2.00–11.37]
Sleep problems****	11.99 [3.46–41.51]	Sleep Problems**	3.23 [1.40–7.49]
Permanent awareness of tinnitus***	10.61 [2.43–46.29]	Pain*	2.84 [1.20–6.73]
Binaural tinnitus localization**	4.14 [1.62–10.57]
Somatic Symptom Severity (PHQ-15)*	4.75 [2.43–46.29]

Tinnitus lower with hearing aid*	0.32 [0.15–0.7]

Variables with significant impact on tinnitus-related distress and subjectively perceived tinnitus loudness were determined in a stepwise regression analysis comparing mild versus severe distress and low versus high loudness, respectively. Concordance of the model was 89.7 for tinnitus-related distress and 81.3 for subjective tinnitus loudness. Odds ratios (ORs) and 95% confidence intervals (95% CI) are shown.
