Table 3.

Variance explained by three conditional models that included the factor of RST Group, with and without the covariates (age and hearing loss).

	Independent Variable (p-value)	Covariate Variables (p-value)	Explained Variance
Intercept
Model A	RST Group (p=0.003)		29.3%
Model B	RST Group (p=0.007)	Age (p=0.009)	40.8%
Model C	RST Group (p=0.011)	Age (p=0.056) 4 kHz Threshold (p=0.076)	47.5%
Slope
Model A	RST Group (p=0.027)		21.3%
