Table 2. Heterogeneity of miRNA expressions in PCa in TMA’s.
| miRNA | ICC* | Std. err. | 95% CI |
|---|---|---|---|
| miRNA-21 | 0.525 | 0.087 | 0.358–0.686 |
| miRNA-34a | 0.764 | 0.051 | 0.650–0.850 |
| miRNA-125b | 0.451 | 0.093 | 0.282–0.631 |
| miRNA-126 | 0.653 | 0.068 | 0.512–0.771 |
| miRNA-143 | 0.627 | 0.072 | 0.478–0.754 |
| miRNA-145 | 0.722 | 0.060 | 0.591–0.823 |
ICC: interclass correlation
PCa: Prostate cancer, TMA: Tissue microarray
* High ICC means higher correlation between cores within patients, leaving most of the overall variation attributable to differences between patients (= biological variation)
