NOTE: Performance of the genes was analyzed by AUC of the genes for the 2 contrast groups. Sensitivity and specificity are reported for the threshold that minimized sensitivity–specificity. The P value indicates the statistical significance. Location of the CpG site used for analysis is given with respect to the distance from the transcription start site. The CpG island location on the respective chromosome is shown.
Abbreviation: CI, confidence interval.
↵at test P value is obtained by comparing tumor (n = 158) and benign tissues (n = 34).
↵bt test P value is obtained by comparing prostate cancer tissues of patients with recurrence (n = 98) and without recurrence (n = 60).
↵ct test P value is obtained by comparing prostate cancer tissues of patients with clinical recurrence (n = 59) and biochemical recurrence (n = 39).
↵dt test P value is obtained by comparing prostate cancer tissues of patients with systemic recurrence (n = 23) and local recurrence (n = 36).
