Rate ratios (RR) of episodes of work absence (n=395) in relation to work hours.

Characteristics	Unadjusted		Age-adjusted		Multivariable-adjusted
	RR	95% CI	RR	95% CI	RR	95% CI
	Episodes of work absence (one-day)1
Overtime hours per week	0.91	0.86 – 0.96	0.90	0.86 – 0.95	0.92	0.87 – 0.98
Total work hours per week	0.96	0.92 – 0.99	0.94	0.91 – 0.98	0.95	0.92 – 0.98
	Episodes of work absence (≥3 consecutive days)2
Overtime hours per week	0.93	0.87 – 0.98	0.92	0.87 – 0.98	0.94	0.88 – 0.99
Total work hours per week	0.91	0.88 – 0.93	0.91	0.88 – 0.93	0.92	0.89 – 0.95

¹For the multivariable-adjusted model, adjustment was made for age, gender, race, smoking status, rank, and sleep hours.

²Adjustment was made for age, gender, rank, education, BMI, alcohol consumption and number of children.
