Notes: We downloaded all the data of TCGA-PRAD data set. Among the 499 prostate cancer samples, the expression value of PF4V1 was available for 498 patients. The data of “Age” and “Gleason score” were complete for all the 498 patients. However, other data were not available for all these 498 patients. The TCGA-PRAD data set only provides “PSA level” data from 441 patients, “T stage” data from 399 patients, “N stage” data from 425 patients, and “M stage” data from 459 patients.
