*median (range) unless otherwise specified

a Total exceeds 16 because more than one possible mode of infection was documented in some patients

b One patient could only walk half distance. For the analysis their timed walk was doubled

c One patient in each group is excluded from the analysis because they had an indwelling urinary catheter.

A further 5 patients (3 in placebo group, 2 in active group) have missing nightly frequencies. Values given as average daily/nightly urinary frequency between screening and week 0

d Baseline data only available on n = 6 in placebo group and n = 7 in active group

e Baseline data only available on n = 7 in placebo group and n = 7 in active group
