Data are presented as number (percentage) of participants if not stated otherwise. Bacteria are sorted by the prevalence in smokers. Significant difference between groups in bold font. Abbreviations: p = statistical significance of the prevalence in non-smokers and smokers calculated using the Fisher exact test only for bacteria with the frequency of ≥3; φ = phi coefficient of association.
