Multivariable-adjusted associations of hearing status (referent=normal hearing) and cognitive function (measured by principal component analysis), overall and stratified by hearing loss severity. Results are presented as standardized linear regression coefficients and 95% confidence intervals.

Cognitive Function
	Hearing loss (mild + moderate+) n=1163		Mild hearing loss n=720		Moderate or worse hearing loss n=443
