Although all the 5 models were generated from stage I patients, different T1 and T2 portions might partly influence the modeling because higher dose is needed for T2 stage patients [16, 27], as mentioned before; (2) a wide variety of dose fractionation schemes were implemented for SBRT but the optimal one needed to be further determined.
