We could not see any differences between the cytokine levels stratified for periodontitis in any of the cytokines and chemokines studied (IL‐1β (n = 114, p = .234), IL‐4 (n = 104, p = .173), IL‐6 (n = 103, p = .223), IL‐10 (n = 123, p = .522), IL‐17A (n = 119, p = .731), INF‐γ (n = 124, p = .637), MCP‐1/CCL2 (n = 103, p = .247), eotaxin (n = 123, p = .613), TNF‐α (n = 103, p = .364) and RANTES/CCL5 (n = 103, p = .087)). Here, IL4 is linked to periodontitis.
