The Correlation between FSTL1 Expression and Airway Remodeling in Asthmatics

Figure 5

Relationships between FSTL1 levels in plasma and BALF and airway remodeling. Correlation between α-smooth muscle actin and (a) plasma FSTL1 concentration and (b) BALF FSTL1 concentration. Correlation between fibrosis levels and (c) plasma FSTL1 concentration and (d) BALF FSTL1 concentration. Correlation between basement membrane thickness and (e) plasma FSTL1 concentration and (f) BALF FSTL1 concentration. Correlation between collagen I levels and (a) plasma FSTL1 concentration and (b) BALF FSTL1 concentration. Correlation was determined by Spearman rank correlation analysis.
