Figure 4.

Effect of competition on the net gain or loss of patients for each radical prostatectomy centre during the study period

The size of the circles corresponds to the number of men expected to have surgery at the centre. Red circles correspond to centres that closed during the study period (2010–14). Green circles correspond to established robotic centres. Blue circles correspond to centres that were neither robotic radical prostectomy centres nor centres that closed during the study period. Spatial competition index (SCI) score 0=hospital facing weakest competition. SCI score 1=hospital facing strongest competition.
