CRP and periodontitis: At an 11-year follow-up, unadjusted regression models demonstrated associations between elevated CRP levels and advanced periodontitis (<i>β</i> = 0.19; 95% CI 0.08-0.31 and <i>β</i> = 0.20; 95% CI 0.09-0.31) or advanced periodontitis combined with low BSDS (<i>β</i> = 0.23; 95% CI 0.09-0.37) or proinflammatory diet (<i>β</i> = 0.18; 95% CI 0.02-0.34).
