Summary of univariate correlation results across five studies.
| Dataset | Number of genes | # genes most correlated with themselves | # genes most correlated with genes from the same chromosome |
|---|---|---|---|
| Pollack | 4841 | 42 (0.90%) | 619 (13.21%) |
| Hyman | 6823 | 28 (0.41%) | 648 (9.50%) |
| Heidenblad | 8879 | 8 (0.09%) | 713 (8.03) |
| Zhao | 14284 | 3 (0.02%) | 853 (6.09%) |
| Kim | 21066 | 79 (0.5%) | 2344 (14.0%) |
Notes: In this table, the second column refers to the number of genes in which the largest correlation in magnitude with copy number is that from the same gene (i.e. the same spot on the microarray). The third column refers to the number of genes whose largest correlation between expression and copy number was with a spot that mapped to a gene on the same chromosome.
