Box-whisker representation of the Expanded Prostate Cancer Index Composite bowel domain survey scores at pretreatment and 1, 1.5, and 2 years posttreatment. Score decrease from pretreatment to 1 year was statistically significantly different (P < .001). There was no significant further decrease in score. Solid bolded black lines indicate median scores. Upper and lower box edges indicate 75th and 25th percent quartile score, respectively. Whiskers indicate 1.5 times the interquartile range of the box. Circular data points indicate individual recorded scores falling outside the boxes and whiskers.
