Changes in Quality of Life after Carbon ion Treatment of Prostate Cancer. The graphs show unadjusted changes in mean QOL scores over time for each domain, as measured by the EPIC-26. The error bars represent standard deviations. The scores are on a 0 to 100 scale, with higher values meaning a more favorable health-related quality of life. Asterisks (*) designate time point at which scores significantly differed from baseline (p < .01, to account for Bonferroni adjustment) and were significantly clinical relevance. Daggers (+) designate time points at which differences were clinically significant but were not statically significant. Double daggers (‡) designate mean scores that showed improvement over pretreatment levels
