Effects of single radiation treatment on tumour growth. A Modified growth delay to four-fold of starting volume after fractionated irradiation. Given are Kaplan-Meier-plots of tumours after treatment with increasing doses of fractionated irradiation (open diamonds, control; grey diamonds, 5 x 2 Gy; dark grey diamonds, 5 × 3.5 Gy; black diamonds, 5 × 4.5 Gy). B Respective computed median growth delay with 95%-confidence interval (n=7-8), * indicates p<0.05 vs. control. C Modified growth delay to eight-fold of starting volume after fractionated irradiation. Given are Kaplan-Meier-plots of tumours after treatment with increasing doses of fractionated irradiation (open diamond, control; grey diamond, 5 × 2 Gy; dark grey diamond, 5 × 3.5 Gy; black diamond 5 × 4.5 Gy). D Respective computed median growth delay with 95%-confidence interval (n=7-8), * indicates p<0.05 vs. control.
