Risk Factors for Reduced Salivary Flow Rate in a Japanese Population: The Hisayama Study

Table 3

Predictors of rate of reduction in salivary flow during the follow-up period determined by using stepwise multivariable linear regression.

		SE	Standardized		value
Salivary flow rate (mL/min)	0.116	0.009	0.348	12.952	<0.001
Age per decade^a	0.058	0.011	0.132	5.100	<0.001
Sex (men = 0; women = 1)	0.116	0.024	0.132	4.853	<0.001
Plaque score (<1 = 0; ≥1 = 1)	0.065	0.026	0.066	2.526	0.012

The analysis also included use of antihypertensive agents, which was excluded in the final model.
Parameters of model: = 46.858; adjusted = 0.118; < 0.001.
