Number and percentage of cases and controls carrying the periodontal pathogen.

Odds ratios (ORs), 95% confidence intervals (CIs), and P values were calculated from conditional logistic regression with non-carriers as the reference, adjusted for unmatched covariates including smoking pack-years, alcohol drinking status, total energy intake, BMI, last time of dentistry visit, sequencing batch, and sequencing depth
