From: The effect of smoking on chronic inflammation, immune function and blood cell composition
Smokers have elevated plasma levels of CRP and fibrinogen but not PGE2. Plasma samples were analysed for (a) CRP, (b) fibrinogen and (c) PGE2 ● = non-smoking, controls; All the smokers were given a unique identifying symbol so that each smoker could be tracked from one assay to another. As well, all males were symbolized by a square and all females by a circle. The mean is shown as a horizontal line within each group. * indicates a statistically significant difference (P < 0.05) between smokers and the non-smoking control group.
