Figure 4. Correlation of FST expression to patient survival. (A) Relapse-free survival is better in tumours with higher FST expression (p<0.001). (B) Overall patient survival over 5 years follow-up shows significantly better survival in those with higher FST expression (p=0.007). (C) Overall patient survival over 10 years and (D) 20 years follow-up do not reach statistical significance in terms of survival difference (p=0.06), but does show a similar trend regarding better survival with higher FST expression.
