IL-6 was associated in the asthma group with age (β = 0.19 [95% CI, 0.11–0.27]) and BMI (β = 0.25 [95% CI, 0.17–0.32]), as well as hsCRP (β = 0.6 [95% CI, 0.54–0.67]), fibrinogen (β = 0.29 [95% CI, 0.22–0.37]), TNFα (β = 0.29 [95% CI, 0.22–0.37]), and ETP (β = 0.35 [95% CI, 0.28–0.42]). This evidence concerns the gene TNF and asthma.
