Smoking status Unweighted Unifrac Weighted Unifrac Bray–Curtis Omnibusb
Former vs. never 0.6869 0.6586 0.7917 0.8480
Current vs. never 0.0941 0.5342 0.2413 0.2210
Smoking dosage (pack) 0.2241 0.8524 0.6630 0.3630

aThe model has been adjusted for sex, age, body mass index, betel quid use, and education.

bThe omnibus test simultaneously considers unweighted Unifrac, weighted Unifrac and Bray–Curtis distances.
