Table 3.
Number of differentially expressed probes (based on spot identification) identified by each laboratory using its own method of normalization (A) and identified using the same analysis pipeline performed by the benchmark laboratory, laboratory 1 (B)a
| Lab 1 | Lab 2 | Lab 3 | Lab 4 | Lab 5 | Lab 6 | |
|---|---|---|---|---|---|---|
| A | 9534 | 11846 | 9889 | 3488 | 6868 | 9743 |
| B | 9534 | 12244 | 6598 | 2498 | 5927 | 7044 |
| C | 6048 | 2375b | 2886 | 3934 | 4632 | |
| D | 77% | 30%b | 37% | 50% | 59% |
a
Number of probes in common with laboratory 1 (C), given also as a percentage (D). The targets on the fathead minnow microarray represent both duplicate and nonduplicated genes (thus, “probe ID” is the value in Table 3). All data are based on false discovery rate corrected p values.
b
Non–false discovery rate data used.
