Differentially expressed probes in prostate tissue.

Probe numbers that have satisfied the comparison criteria of fold change and P-value cutoffs are shown. Numbers in parentheses represent the median false discovery rate calculated in dChip after 100 permutations of the samples.
*P-values were calculated in dChip by a Welch modified two-sample t-test. n = 18 for Benign, n = 14 for Malignant; n = 4 for GSTM1(+) Benign, n = 14 for GSTM1(−) Benign; n = 5 for GSTM1(+) Malignant, n = 9 for GSTM1(−) Malignant; n = 7 for GSTM1(+) Pre-intervention, n = 3 for GSTM1(−) Pre-intervention; n = 6 for GSTM1(+) 6-month broccoli, n = 5 for GSTM1(−) 6-month broccoli; n = 3 for GSTM1(+) 6-month pea and n = 5 for GSTM1(−) 6-month pea intervention.
**P-values were calculated in dChip by a Welch modified two-sample paired t-test, n = 4 for each of the diet interventions.
