Adjusted Odds Ratios quantifying chance of being periodontally diseased depending on detection (yes/no) or abundance of different pathogens in tongue scrapings in the overall study population (N = 88 pairs).

Conditional logistic regression modeling periodontal status (cases versus controls, dependent variable) on detection (yes/no) or abundances adjusting for age (cont.), school education, smoking status and BMI.◊Abundances were categorized as tertiles (T1–T3). Numbers within tertiles were: P. gingivalis: 75-43-58, A. actinomycetemcomitans: 92-26-58, F. nucleatum: 93-25-58, S. sanguinis: 75-43-58, Archaea 85-33-58, %Archaea: 85-33-58, Bacteria: 59-59-58.1proportion of 16S rRNA gene copies per ng extracted DNA; N, number of matched pairs.2percent of archaeal 16S rRNA gene copies per prokaryotic 16S rRNA gene copies (Archaea+Bacteria)*100.*p
