Taxonomy	Odds ratioa (95% CI)	p value	FDR-adjusted p value†
Class Alphaproteobacteria	4.85 (1.53, 15.39)	.01	.04
Order GMD14H09	0.30 (0.11, 0.82)	.02	.19

CI = confidence interval.

^aOdds ratio of the presence probability of taxa comparing current smokers to never-smokers adjusting for age, sex, body mass index, education, and betel quid use using logistic regression based on the dichotomous variable for presence/absence of taxa with a prevalence of greater than 10% and less than 90%. A total of 142 bacterial taxa were tested. Only the ones with nominal significance were listed.

^† p values were corrected for multiple testing using the Benjamini–Hochberg procedure to control the false discovery rate (FDR) ≤5%.
