Table 3.
Pearson correlation coefficients of the geometric mean of the erythropoiesis gene-expression signature values and different PBMC subpopulations across all available samples (n = 152)
| PBMC subpopulation/ratio | r (Pearson) | Correlation P value |
|---|---|---|
| CD34+ | 0.48 | < 0.001 |
| CD34+CD33- | 0.45 | < 0.001 |
| CD15+CD16- | 0.45 | < 0.001 |
| CD34+CD33+ | 0.36 | < 0.001 |
| NK bright/dim ratio | 0.38 | < 0.001 |
| CD15+CD16+ | 0.38 | 0.04 |
|r| > 0.5 represents a large degree of correlation, 0.3 < |r| < 0.5 represents a moderate degree of correlation and 0.1 < |r| < 0.3 represents a small degree of correlation; |r| < 0.1 represents a lack of correlation (upper panel). Only PBMC subpopulations are shown for which P was < 0.05. A low P value indicates that the observed correlation coefficient is due to a statistically significant relation between the two variables.
