Figure Legends
Figure 1 – Figure 1A shows the stress scale. Figure 1B shows the physical activity levels. Figure 1C shows the levels of sleepiness by Epworth sleepiness scale. The results were expressed as mean ± SD.
Figure 2 – Figure 2A shows the values of forced vital capacity (FVC). Figure 2B shows the values of forced expiratory volume in the first second (FEV1). Figure 2C shows the values of FEV1/FVC. Figure 2D shows the values for peak expiratory flow (PEF). Figure 2E shows the values for mean expiratory flow at 25% of FVC curve. Figure 2F shows the values for mean expiratory flow at 50% of FVC curve. Figure 2G shows the values for mean expiratory flow at 75% of FVC curve. Figure 2G shows the values of inspiratory vital capacity. The results were expressed as mean ± SD.
Figure 3 – Figure 3 shows the levels of exhaled nitric oxide. Results are expressed in parts per billion (ppb). The results were expressed as mean ± SD.
Figure 4 – Figure 4 shows the levels of cytokines in the breath condensate. Figure 4A shows the levels of IL-2. Figure 4B shows the levels of IL-10. Figure 4C shows the levels of IL-17. Figure 4D shows the levels of IFN-gamma. The results were expressed as mean ± SD.
Figure 5 – Figure 5 shows the levels of cytokines and desoxicortisol in the serum. Figure 5A shows the levels of IL-2. Figure 5B shows the levels of IL-10. Figure 5C shows the levels of IL-17. Figure 5D shows the levels of IFN-gamma. Figure 5E shows the levels of desoxicortisol. The results were expressed as mean ± SD.
