Data Set 1: Tinnitus Data Registry, 1981 - 1994 More Tinnitus Test Results Data Summaries

Overall Sample Number: 1630

Number of patients responding to this item: 1257sample subset.gif: When the sample size for the current analysis is substantially (more than 10%) smaller than the total number of patients in the database, this will appear to flag that fact.
Test Conditions:       

Test ear was contralateral to predominant tinnitus if tinnitus was lateralized; if
not lateralized, test ear was chosen arbitrarily.
