A similar pattern was found for the slope of the association between the number of eosinophils per milligram of sputum and the level of exposure to NO 2 , which was not significant at day 1 ( p = 0.10), close to significance at day 2 ( p = 0.06), and significant at day 3 ( p = 0.03) ( Table 3 ; see also Supplemental Material, Figure S1).
