Cytokine levels in serum from patients with periodontitis or gingivitis, or from healthy controls. Serum from patients with chronic periodontitis (n = 15) or aggressive periodontitis (n = 15), as well as periodontally healthy controls (n = 13) was analysed. Cytokine levels in 25 µl of serum were determined by Luminex. Each symbol represents an individual subject; the median and interquartile range is shown, dotted lines indicate the minimum detectable concentration of that particular mediator. Log‐transformed data were analysed by one‐way analysis of variance with Bonferroni’s multiple comparison test. *P<0.05.
