Diabetes and Risk of Hearing Impairment in Adults: A Meta-Analysis

JCEM: November 12, 2012

Context: Recently, several studies have investigated the relationship between diabetes and hearing impairment, but results were inconsistent.

Objective: Our objective was to compare the prevalence of hearing impairment between diabetic and nondiabetic adults.
