Fig. 2. (A) Positive correlations between miRNA-29b expression in serum and FeNO (ppb). (B) Decreases in serum miRNA expression in patients with low (FeNO < 25 ppb) as compared to patients with high (FeNO > 25 ppb) levels of airway inflammation at the EV. Differences were analyzed using the Mann-Whitney U test.
miRNA, microRNA; FeNO, fractional exhaled nitric oxide; ppb, parts per billion.
