CAD = Coronary Artery Disease, SD = Standard Deviation, L = liter, fL = femtoliter, dL = deciliter, G = gram, pG = picogram, COPD = Chronic Obstructive Pulmonary Disease. For Student's T-test, automated cell counting values were recalculated as values per gram or liter, and log2 normalized prior to determination of p-Value.
* Fisher's Exact Test shows significant differences between low and high cotinine at p = 0.0315 (2-tail)
