Table 3.
Average and standard deviation results for the DVH shape-based metrics for each organ at each campus. Bolded and italicized values represent regional sites that statistically differed (p < 0.05) from MC for that metric. The lungs displayed the most consistency and the stomach the least consistency between each RS and MC.
| Organ | Campus | P = % DVH bins outside predicted band (avg +/− SD)(%) [p-value] |
F =% DVH bins outside worse than prediction (avg +/− SD) (%) [p-value] |
mRSR = net DVH area between planned and predicted DVH (avg +/− SD) (Gy) [p-value] |
