Table 5 Comparison between risk factors for LBP radiating below the knee vs other LBP for men

	Men
	LBP without pain radiating below the knee	LBP radiating below the knee	p Value†
	OR* (95% CI)	OR* (95% CI)	p Value†
Driving a car >2 h/day	1.01 (1.00 to 1.02)	1.01 (0.99 to 1.03)	NS
Bending/twisting	1.01 (1.00 to 1.03)	1.01 (0.99 to 1.03)	NS
Pushing/pulling/carrying heavy loads	1.00 (0.99 to 1.02)	1.03 (1.01 to 1.05)	0.0198

NS, not significant.
*OR for one year of exposure, adjusted for age, BMI, headache, psychosomatic problems.
