  1. Values are means (SD).
  2. *Median test for white blood cell count in male and female smokers. Comparisons are between three levels of airway obstruction reflected by FEV1%. (P < 0.001)
  3. BMI: Body mass index (kg/m2).
  4. FEV1(%): Forced vital capacity expressed as a percentage respect to normal value.
