The reduction in the mean SD along all three axes from 6.4 mm to 3.1 mm was highly significant ( p = 0.001 ) .
The reduction in the mean SD along all three axes from 6.4 mm to 3.1 mm was highly significant ( p = 0.001 ) .
Maximum field displacement changes for SI (100.8 mm to 17.0 mm) and AP (22.4 mm to 12.2 mm) were reduced markedly on the days with the greatest setup error, and showed a trend toward reduction overall ( p = 0.17 and p = 0.13 , respectively).
