The OARs were divided into several suborgans, and SPSS software was used to evaluate multiple linear method for fitting the normalized volume for each suborgan, normalized mean dose (Dmean) Dnm (Dnm = Dmean\/Dprescription), and normalized D10%\u2212D100% values Dn10% \u00a0\u2212 \u00a0n100%(Dn10%\u2212n100% = D10%\u2212D100%\/Dprescription) for each OAR.
