Figure 3. Overall Quality-Adjusted Product-Limit Survival According to Treatment.

Figure 3.

The Q-TWiST method was used to analyze quality-adjusted overall survival time, that is, the proportion of patients alive without significant toxic effects (all MD Anderson Symptom Inventory [MDASI] scores <5) over the interval since randomization, in months. The shaded areas represent interval confidence limits. MFRT indicates standard-dose multifraction radiation therapy (10 fractions of 3 Gy each, for a total of 30 Gy); SBRT, high-dose, single-fraction stereotactic radiation therapy with a dose of 12 Gy or 16 Gy (solid line).
