Aa, Aggregatibacter actinomycetemcomitans; Pg, Porphyromonas gingivalis; CRP, C-reactive protein; LPS, lipopolysaccharide; AAA, abdominal aortic aneurysm.
(a)
CRP level expressed in log10 of no. of proteins (mg/ml)
(b)
LPS amount expressed in log10 of no. of endotoxin (LPS/ml).
(c)
All antibodies amounts expressed in log10 of no. of genome equivalents (Geq/ml).
(d)
AAA diameters and volumes log-transformed.
(e)
Regression coefficients derived by linear regression adjusted for group (stable/unstable); a positive (negative) coefficient indicates an increasing (decreasing) relationship between pathogens and diameters/volumes.
