Psychometric evaluation of the Nocturia Impact (NI) Diary was conducted to support its use as a trial endpoint.
As part of a randomized, controlled Phase 2 clinical trial investigating a novel drug candidate for nocturnal polyuria, adult nocturia patients completed the NI Diary and a voiding diary for three nights preceding their clinic visit at Baseline and Weeks 1, 4, 8, and 12 (end of treatment).
