Fig 1. Comparison of serum syndecan-4 levels in healthy volunteers and in patients with SD-IIP and AE-IIP.

Fig 1

Serum syndecan-4 levels were significantly higher in the SD-IIP group than in the HV and AE-IIP groups. Serum syndecan-4 levels did not differ between the HV and AE-IIP groups. HV: healthy volunteer group, SD-IIP: patient group with stable idiopathic interstitial pneumonia, AE-IIP: patient group with acute exacerbation of idiopathic interstitial pneumonia. ANOVA with Tukey HSD was used for statistical analysis. *: p < 0.05 vs HV. †: p < 0.001 vs AE-IIP. Data are expressed as means ± the standard error of the mean (SEM).
