Fig. 3

Distribution of sTREM-1 levels in GCF from healthy sites (n = 17), gingivitis-affected sites (n = 19), and periodontitis-affected sites of patients with CP (n = 15). sTREM-1 levels in the GCF samples were determined by ELISA. Individual values represent sTREM-1 as pg/mg of protein after normalization of the ELISA read-outs to total protein levels (a), sTREM-1 total amounts (pg) (b), or sTREM-1 concentrations (pg/μL) calibrated against corresponding GCF volume (c). Horizontal lines indicate the median values
