Analysis of collagen and elastic vascular fibres stratified by histological patterns of idiopathic interstitial pneumonia (IIP) and control lung
| Vascular collagen/elastic system | ||||
|---|---|---|---|---|
| Mean | SD | SE | 95% CI for mean | |
| DAD, diffuse alveolar damage; IIP, idiopathic interstitial pneumonia; NSIP, non-specific interstitial pneumonia; UIP, usual interstitial pneumonia. | ||||
| Results analysed by the one-way analysis of variance (ANOVA) procedure and Bonferroni multiple comparisons post hoc tests for ANOVA vascular collagen/elastic system fibres and their distribution in the histological patterns of IIP and control lung with level of significance 0.05. | ||||
| *Control versus DAD, p<0.001; DAD versus NSIP, p<0.001, NSIP versus UIP, p = 0.009. | ||||
| †Control versus DAD, p<0.001; DAD versus NSIP, p = 0.08; NSIP versus UIP, p<0.001. | ||||
