Time point (hr) | No. of twofold or greater changes | % total changes | Probability of being different from 1 to 3 hr |
---|---|---|---|

1–3 | 64/2179 | 2.94 | — |

6–8 | 9/113 | 7.96 | 0.008 |

12 | 13/169 | 7.69 | 0.003 |

The total number of genes exhibiting twofold or larger changes in magnitude is shown over the total number of significantly differentially regulated genes (using

*Q*-value cutoff) at each time point and the percentage of each of these fractions is given. The probability of this value being significantly different from the 1- to 3-hr time point (from Fisher's exact test).
