The association between cigarette smoking and gut microbes at the genus level (16S rRNA). a The Venn plot illustrates the number of genera with nominal p less than 0.05 in each of the four studies using MaAsLin2. The estimations involved the comparison between current smokers and non-smokers, with adjustments for age and BMI. b-d The forest plots display the meta-analysis results of association between b smoking status (current smokers vs. non-smokers), c the duration of smoking in years, and d the number of cigarettes smoked per day and genera. Genera with Bonferroni-corrected p less than 0.05 or showing overlap across studies are showed. The fixed-effects model was utilized, and heterogeneity was assessed using I2 and Cochran-Q tests
