Lung cytokine and chemokine levels. Box-and-whisker plot of lung cytokine/chemokine in the four experimental groups: control (CO; n = 10), control with exercise (EX; n = 15), aerosolized ovalbumin (SS; n = 20), and SS and exercise (EXS; n = 22). The box represents the first quartile, the median, and the third quartile; the whisker extends to 1.5 times interquartile range (the difference between 1st and 3rd quartiles), the asterisk is the mean, and the circles are outliers. Significant overall group differences were found in growth related oncogene/keratinocyte/chemoattractant (GRO/KC; P < 0.0001), TNFα (P = 0.0003), IL-1α (P < 0.0001) and IFN-γ (P < 0.0001). Post hoc paired comparison results: #SS group significantly higher than all other three groups; $SS group significantly higher than EX group; and &Control group significantly lower than all other three groups.
