Table 1 Patient demographics

From: Smoking-induced gene expression changes in the bronchial airway are reflected in nasal and buccal epithelium

  Buccal Microarray (n = 10) Nasal Microarray (n = 15)
  Smokers n = 5 Never n = 5 P-Value Smokers n = 7 Never n = 8 P-Value
Sex 1 M, 4 F 2 M, 3 F p = 0.42 6 M, 1 F 6 M, 2 F p = 0.58
Age 36 (+/- 8) 31 (+/- 9) p = 0.36 47 (+/- 12) 43 (+/- 18) p = 0.46
Race 3 CAU, 2 AFA 2 CAU, 3 AFA p = 0.40 3 CAU, 3 AFA, 1 HIS 5 CAU, 2 AFA, 1 HIS p = 0.73
  1. Demographic data for patient samples used in the microarray studies (n = 25). Clinical information including sex, age, and race are included (CAU – Caucasian, AFA – African American, HIS – Hispanic). Statistical comparisons were performed between smokers vs. nonsmokers within each tissue type. P-values for sex and race were determined by Fisher exact test.
