Difference in hearing thresholds according to the presence of metabolic syndrome.

Data are expressed as mean ± standard deviation. *P values between MetS (-) and MetS (+) were tested using the t-test. Abbreviations: MetS (-), absence of metabolic syndrome; MetS (+), presence of metabolic syndrome; Low-Freq, low-frequency; Mid-Freq, mid-frequency; High-Freq, high-frequency; dB, decibel.
