Figure 6. Unadjusted Health-Related Quality of Life for Men With Favorable- and Unfavorable-Risk Disease in a Study of the Association Between Treatments for Localized Prostate Cancer Through 5 Years .

Domain scores are from the Medical Outcomes Study Short Form 36. Domain scores are scaled from 0 to 100, with higher score indicating better function. A minimum clinically important difference in score is 7 on the physical functioning, 6 on the emotional well-being, and 0 on the energy and fatigue domain. The boxes indicate the lower and upper quartiles and the lines inside the boxes indicate the median. The whiskers extend to the furthest points from the lower and upper quartiles that are still within 1.5 × the interquartile range (upper quartile − lower quartile). All the points beyond 1.5 × interquartile ranges are shown as dots, the intensity of which signifies the relative number of participants with that value.
