Threshold BED₂ according to fractionation regimen in patients with liver cirrhosis. (A) Threshold BED₂ values were plotted according to the number of fractions in cirrhotic patients. Error bars indicate the medians with interquartile ranges. Fractionation regimen was not significantly correlated with hepatic dysfunction (P = 0.1019). (B) Total radiation dose was plotted against the number of fractions in cirrhotic patients with Child–Pugh scores of 5 and ≥ 6. The solid line indicates a BED₂ of 40 Gy. BED = biologically effective dose.
