Figure 2. Adjusted Prostate Cancer Specific Survival Rate Difference at 10 year by Treatment.

Figure 2

The mid-point of the box represents the point effect estimate, that is, the adjusted population average cancer-specific difference at 10yr between high and low radiation use area. The area of the box represents the sample size of each treatment group. The larger box size represents the larger sample size. The width of the line shows the 95% confidence intervals (CI) of the effect estimate of individual treatment. The 95% CI was computed from 1000 bootstrap samples. The arrow showed the lower and upper limits for clipping confidence intervals. External beam radiation therapy included 3D conformal radiotherapy (3D CRT), intensity modulated radiation therapy, proton beam therapy or unknown type therapy. The result of 3D CRT was similar to that of External Beam Radiation.
