An observational study in Tinnitus, sponsored by Eye & ENT Hospital of Fudan University. Completed. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-10-22.
Sponsored by Eye & ENT Hospital of Fudan University · Observational
This retrospective observational study will use historical electronic health record and tinnitus specialty database data from adult patients with tinnitus seen at the Eye and ENT Hospital of Fudan University between January 2015 and August 2026. The study will identify multidimensional tinnitus phenotypes, examine relationships between subjective tinnitus severity and objective audiometric measures, explore within-phenotype heterogeneity, and assess longitudinal phenotype stability and outcome patterns using existing follow-up records. No intervention or additional examination will be performed.
421 studies on the registry are indexed under Tinnitus; 88 are open to participants now.
This study's enrollment of 225,792 is above the median of 100 across 55 observational studies indexed under Tinnitus.
