TSLP and asthma: The adjusted multivariate logistic regression model revealed that previous history of severe-to-serious asthma exacerbation, serum tryptase level of ≤ 1448 pg/mL, serum TSLP level of ≥ 25 pg/mL and blood eosinophil count of ≥ 291cells/μl, were the independent factors predictive for asthma exacerbation with an AOR of 3.27, 2.53, 8.67 and 6.04, respectively.
