Association of peripheral hearing loss and incident cognitive impairment (in relation to: the ear sides associated with PTA results, maximum follow-up of each cohort, racial and sexual distributions of each cohort, statistical adjustment, and hearing and cognitive evaluations each cohort had applied).

|---|---|---|
| Ear sides (PTA) | −0.14 (−0.36–0.08) | 0.188 |
| Maximum follow-up | 0.33 (0.13–0.53) | 0.004 |
| Ethnicity | −0.02 (−0.66–0.61) | 0.942 |
| Gender | 0.15 (−0.15–0.44) | 0.294 |
| Adjustment | −0.01 (−0.10–0.08) | 0.829 |
| Hearing measures | 0.61 (−0.75–1.97) | 0.345 |
| Cognitive evaluations | −0.35 (−1.44–0.74) | 0.496 |
