Associations between salivary cotinine and detection rates for salivary Pb and Ni.

	Pb	Ni
	b, 95% CI	b, 95% CI
Cotinine*	1.40, (0.424 to 2.459)	0.288, (-0.5431 to 1.103)
Sex	(−)0.302, (−1.254 to 0.623)	(−)0.309, (−1.091 to 0.4506)
BMI	(−)0.107, (−0.285 to 0.037)	(−)0.035, (−0.1618 to 0.07423)
Race	(−)0.761, (−1.764 to 0.201)	(−)0.886, (−1.738 to −0.07189)
INR	(−)0.044, (−0.421 to 0.237)	(−)0.027, (−0.3000 to 0.2014)

Associations were determined by multiple logistic regression. Statistically significant findings are shown in bold font. Metals outcome values were dichotomized by detection limit. *cotinine was coded 0 for values less than 1 ng/ml and 1 for >1 ng/ml. BMI body mass index. INR income-to-needs ratio.
