The serum level of anti-BPDE-DNA before and after the therapy (nonsmokers).

CCT content	Anti-BPDE-DNA		Statistical significance of differences
	Before GT	After GT
CCT-3% (𝑛=12)	0.23 (0.17–0.30)	0.28 (0.19–0.43)	𝑃<𝟎.𝟎𝟎𝟏
CCT-5% (𝑛=18)	0.34 (0.28–0.47)	0.38 (0.30–0.50)	𝑃<𝟎.𝟎𝟓
Statistical significance of differences	𝑃<𝟎.𝟎𝟓	NS

Anti-BPDE-DNA values (expressed as the EI) are presented as median (lower–upper quartile) because of nonnormal data distribution; 𝑛: number of subjects; 𝑃: Wilcoxon matched-pairs test.
