Of the 12 variables entered into the multivariable model, high blood calcium (HR, 0.084; 95% CI, 0.038–0.186), albumin (HR,0.239; 95% CI, 0.187–0.305), SBP (HR, 0.577; 95% CI, 0.403–0.825), thyroid hormone (T3) (HR, 0.593; 95% CI, 0.458–0.769), and alpha fetoprotein levels (HR, 0.883; 95% CI, 0.803–0.971) were potent protective factors for the development of ARHI. Here, AFP is linked to presbycusis.
