†
Note that if p ≤ B&H Threshold, the null hypothesis is rejected.
The Benjamini and Hochburg false discover threshold is listed for each comparison. Note that if the p-value is less than the B&H threshold†, the null hypothesis should be rejected with the assurance that the overall false discovery error rate (i.e., rate for rejecting the null hypothesis when the null hypothesis is true) for the complete set of null hypothesis tests will be no > 0.05 (i.e., 5%).
