Table 2. Associations between the effort-reward imbalance ratio and the number of decayed, missing, and filled teeth after imputation.

		First source population (employees at a medical university)
		(n = 184)
Linear regression models		Age and sex-adjusted model			Fully adjusted model
Dependent variable	Independent variable	Unstandardised coefficient	95% CI	p-value	Unstandardised coefficient	95% CI	p-value
Decayed, missing, and filled teeth (DMFT)	Effort-reward imbalance ratio	−2.50	[–4.30 to −0.69]	0.007	−2.81	[−4.70 to −0.92]	0.004
Decayed teeth (DT)	Effort-reward imbalance ratio	0.00	[−0.26 to 0.26]	0.990	−0.06	[−0.34 to 0.21]	0.645
Filled teeth (FT)	Effort-reward imbalance ratio	−2.45	[−4.08 to −0.82]	0.003	−2.57	[−4.28 to −0.87]	0.003
Missing teeth (MT)	Effort-reward imbalance ratio	−0.05	[−0.71 to 0.62]	0.887	−0.17	[−0.88 to 0.53]	0.627

Notes:

The fully adjusted model included age, sex, smoking status, annual household income, education, years of service with the current company, job type, occupational status, and working hours per week.

CI, confidence interval.
