Scatterplots with selected correlations between pro-inflammatory markers and objectively assessed social-cognitive measures in people with multiple sclerosis (MS) and matched healthy control (HC) participants. Figures show pro-inflammatory markers from urine IP-10 and TASIT-S Part 2 Sarcasm (A) and Part 3 Sarcasm (B), MIP-1β and TASIT-S Part 2 Sarcasm (C) and Part 3 Sarcasm (D), PDGF-bb and TASIT-S Part 2 Sarcasm (E) and Part 3 Sarcasm (F), VEGF and TASIT-S Part 3 Sarcasm (G) markers, and pro-inflammatory markers from serum IL-1β and TASIT-S Part 3 Lies (H), G-CSF and TASIT-S Part 3 Lies (I), and MCP-1 and TASIT-S Part 2 Sincerity (J). G-CSF, Granulocyte colony-stimulating factor; IFNγ, Interferon-gamma; IL-1β, Interleukin 1 beta; IP-10, Interferon-gamma inducible protein 10; IRI, Interpersonal Reactivity Index; IL-17, Interleukin 17; MCP-1, Monocyte chemoattractant protein-1; MCP-1, Macrophage inflammatory protein-1β; PDGF-bb, Platelet-derived growth factor-2 b subunits; TASIT-S, The Awareness of Social Inference Test-Short; TNFα, Tumour necrosis factor-alpha; and VEGF, Vascular endothelial growth factor. Concentrations are shown in fluorescence intensity values for serum and fluorescence intensity/creatinine values for urine.
