^aCotinine Glucuronidation is the ratio of the difference of total cotinine and free cotinine over total cotinine.

^bNE (Nicotine Equivalents) is the sum of total nicotine, total cotinine, and total 3'-hydroxycotinine expressed as nmol/mg creatinine.

^cBeta values and standard errors have been adjusted for age, gender (and race).

^dp-values adjusted for age, gender (and race).
