Fig. 3— Plots of exhaled nitric oxide fraction (FeNO) levels compared with age in a) 876 African-American nonsmokers and b) 98 African-American smokers. FeNO levels and age were log normalised prior to analysis. Linear regression and Pearson's product-moment correlation coefficient were used to examine the relationship between FeNO levels and age. a) r2<0.01, p = not significant; b) r2 = 0.15, p = 0.0001. ––––: derived from the linear regression analyses.
