Fig. 1From: Serum sST2 levels predict severe exacerbation of asthmaSerum sST2 levels and asthma exacerbation risk. a Serum sST2 levels were higher in patients whose asthma was exacerbated within 3 months (at-risk) than those without exacerbation (stable). b Serum sST2 levels correlated positively with the treatment steps defined in the GINA guidelines (2015). c Survival analysis comparing durations until exacerbation between patients with high and low serum sST2 levels. a–c p-values were calculated using the Mann-Whitney test (a), Spearman’s rank correlation (b), and Cox regression analysis (c)Back to article page
