a
NA = not applicable.
b
Data are given as No. (percentage) unless indicated otherwise.
c
Results by cystoscopy/biopsy = positive or evidence of disease.
d
Results by cystoscopy/biopsy = negative or no evidence of disease.
e
Determination of disease diagnosis refers to the method by which the determination of disease absence (cystoscopy negative) was made. The hierarchy of test results is biopsy, rigid cystoscopy, and flexible cystoscopy. The determination of disease presence (cystoscopy positive) can be made only by biopsy.
