Table 1 Agreement of significant genes between "virtual" pooling and no pooling with data from one real experiment. Note: total number of "genes" on the chip = 8799, α = 0.05. Pool size=number of subjects per chip (# subjects per group/ # chips per group)

From: Statistical implications of pooling RNA samples for microarray experiments
