Potential transcription factors essential for prostate cancer progression. (a) Disease-free and (b) overall survival associated transcription factors (p-value < 0.05). (c) Hazard ratios and 95% confidence intervals of hazard ratios of transcription factors in relation to disease-free survival (p-value < 0.05). The x-axis is truncated at −20 and 20. (d) LASSO Cox regression coefficients of transcription factors in relation to disease-free survival. In (c) and (d), a red transcription factor indicates a bad prognosis, whereas a blue transcription factor denotes a protective effect.
