Fig. 3From: Effect of personal exposure to black carbon on changes in allergic asthma gene methylation measured 5 days later in urban children: importance of allergic sensitizationEffects of DNA methylation on FeNO measured 5 days later. Beta coefficient of FeNO and 95% CI for a unit increase in log percent DNA methylation presented. Model adjusted for race/ethnicity, sex, age, asthma diagnosis, obesity, season, and ambient NO on day 6. Sixteen children were removed from the analyses of FeNO and DNA methylation due to either high ambient NO levels (>100 ppb) or equipment failure, resulting in a sample size of 127. *p < 0.05 and **p < 0.01Back to article page
