Table 4. Positive detection rates of each mediator in the tested tear samples.

Mediators	Percentage of tear samples which contained mediators in levels higher than the limit of quantification*
PDGF-bb, IL-1Ra, IL-4, IL-6, IL-7, IL-8, IL-12p70, G-CSF, IFN-γ, IP-10, MCP-1, VEGF	>60%
IL-1β, IL-2, IL-5, IL-9, IL-10, IL-13, MIP-1α, MIP-1β, RANTES, TNF-α	30%–60%
IL-15, IL-17, eotaxin, FGF-b, GM-CSF	<30%

*, limits of quantification are given in Table 1. Abbreviations: IL = interleukin; FGF = fibroblast growth factor; G-CSF = Granulocyte colony stimulating factor; GM-CSF = granulocyte monocyte colony stimulating facotr; IFN = interferon; IP = Interferon gamma-induced protein; MCP = monocyte chemoattractant protein; MIP = macrophage inflammatory protein; PDGF = platelet-derived growth factor; RANTES = regulated on activation, normal T cell expressed and secreted; TNF = tumor necrosis factor; VEGF = vascular endothelial growth factor
