Table 6. Standardized partial regression coefficients (SPRCs) of the Effort–Reward Imbalance (ERI) model indicators on area under the curve with respect to ground (AUC_G) for daytime salivary cortisol, dehydroepiandrosterone (DHEA), and cortisol-to-DHEA molar ratio (C/D ratio).

	ERI model indicator (independent variables)
	Effort score		Reward score		E/R ratio		OC score
AUC_G (dependent variable)	SPRC	P	SPRC	P	SPRC	P	SPRC	P
Cortisol	−0.159	0.151	0.019	0.848	−0.112	0.304	−0.128	0.214
DHEA	−0.061	0.528	−0.002	0.978	−0.041	0.668	−0.049	0.585
C/D ratio	−0.095	0.380	0.038	0.699	−0.078	0.460	−0.080	0.428

E/R ratio: effort-to-reward ratio; OC: overcommitment to work. AUC_Gs were calculated using salivary hormone levels at 9:00, 12:00, and 15:00. SPRCs and P-values were computed with multiple regression analysis, in which age, employment status, current smoking, menstruation irregularity, ovulatory phase, musculoskeletal symptoms, dental and gum diseases, and other health problems were adjusted.
