Abbreviations: CI = confidence interval, IMRT = intensity-modulated radiotherapy.
a
Between means (delta) for area under the curve from 3 to 48 months in each domain and subdomain for the treatments specified, with 95% confidence intervals in parentheses. Radical prostatectomy (open or laparoscopic) is the reference group in all comparisons. A positive score means better function in radiotherapy compared to surgery.
b
The androgen-deprivation group includes radiotherapy patients (external beam or brachytherapy) who also received adjuvant or neoadjuvant hormones of any duration. Patients undergoing radiotherapy plus hormonal therapy are thus represented in both columns.
