Urinary 1-OHP, 3-OHBaP, and 3-OHBaA concentration after creatinine correction.

Analyte	Nonsmokers	Smokers
		8 mg	10 mg	13 mg	Total
1-OHP (ng/g creatinine)	58.16 ± 49.48 ()	62.28 ± 70.58 ()	63.51 ± 68.75 ()	74.88 ± 73.68 ()	66.85 ± 70.91 ()
3-OHBaA (ng/g creatinine)	10.98 ± 4.39 ()	11.01 ± 13.30 ()	9.17 ± 12.89 ()	—	10.35 ± 13.00 ()
3-OHBaP (ng/g creatinine)	1.30 ± 0.20 ()	2.83 ± 1.78 ()	—	6.00 ± 4.44 ()	5.41 ± 4.21 ()

The results were expressed as mean ± standard deviation.
