Squared regression coefficients (r²) and P-values (P) for baseline characteristics of periodontitis patients without statin and those receiving a statin. The values are shown for all pathological periodontal pockets (PPD ≥ 4 mm) and periodontal inflammatory burden index (PIBI). RA stands for rheumatoid arthritis.
