Geometric means of urinary PAH metabolites in lung cancer cases and control subjects among lifelong never smokers, the Shanghai Cohort Study 1986–2008

Urinary PAH metabolite	Geometric mean (95% CI) (pmol/mg creatinine)^a		P
Urinary PAH metabolite	Cases (n = 82)	Controls (n = 83)	P
PheT^b	19.84 (16.16–24.34)	16.10 (13.02–19.88)	0.03
3-OH-Phe	6.64 (5.64–7.80)	5.44 (4.60–6.42)	0.01
Total OH-Phe	19.10 (16.46–22.16)	16.08 (13.78–18.76)	0.02

^aAdjusted for age at baseline, neighborhood of residence at enrollment, years of sample storage and urinary cotinine level.

^bOne case with missing PheT was excluded from this analysis.
