3. Figure 2
Mobility patterns of patients receiving radical prostate cancer surgery at two selected NHS cancer centres
Maps of the UK, illustrating the mobility pattern of patients who received radical prostate cancer surgery at two selected National Health Service (NHS) cancer centres (indicated with a + symbol in the area of core users) located in the east of England (A) and southwest England (B) that had a net gain of patients from outside their local area (ie, more arrivers than leavers). Both centres were established robotic centres. The maps include a scaled magnification of the region inset.

Net gains and losses of patients for each radical prostatectomy centre (n=65) during the study period
Established robotic radical prostatectomy centres (n=12) shown in green and centres that closed during the 2010–14 study period (n=10) shown in red. Centres in blue are centres that were neither robotic radical prostectomy centres nor centres that closed during the study period.

5. 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.
