"Dykstra et al. (2003) studied 15 female patients with overactive bladder (with or without incontinence). The women were treated with botulinum toxin. A t-test for the difference in urinary frequency pre/post treatment indicated that patients experienced an average of 5.27 fewer episodes per day after treatment. The p-value was less than 0.001". The above statement is based on a hypothesis test for the comparison of the means of two independent groups.
