FOXP1 and prostate carcinoma: Both the CSS for prostate cancer and the FFS for DLBCL were derived from only one dataset and neither showed significant associations with the decreased FOXP1 protein expression (HR = 2.51, 95%CI: 0.92–6.83, p = 0.071; HR = 0.71, 95%CI: 0.26–1.94, p = 0.504, respectively).
