Odds ratios for being detectable (concentrations > LOD values, panel A) and concentrations of amino-PAHs (panel B) in relation to occupation status among all study participants. ORs for the diesel engine tester having amino-PAH concentrations above LOD in reference to the non-testers were tested by logistic regressions. Differences in concentrations were tested by linear regressions. Both analyses were adjusted for current smoking, alcohol use, age, and BMI. 1-AP = 1-aminopyrene, 9-Aphe = 9-aminophenanthrene, 2-AF = 2-aminofluorene, 1-AN = 1-aminonaphthalene, and 2-AN = 2-aminonaphthalene.
