PRIMARY outcome

Timeframe: From baseline through 12 Weeks of Intervention

Population: A baseline measure was achieved for Group 1 with 30 patients and Group 2 with 28 patients. At the 12 week measurement period, we were unable to analyze 5 patients in Group 1 (leaving 25 patients) and unable to analyze 3 patients in Group 2 (leaving 25 patients). These participants left for reasons identified in the Participant Flow.

The first part of the OAB-q consists of eight questions assessing symptom bother with a possible score from 0 to 100 with a higher score indicating greater symptom bother.

Timeframe: From baseline through 12 Weeks of Intervention

Population: In Group 1, we were unable to analyze 5 patients and in Group 2 we were unable to analyze 3 patients. These participants left for reasons identified in the Participant Flow.

Assessment made using the Health Related Quality of Life (HRQL) portion of the OAB-q. The second part of the OAB-q, the HRQL consists of 25 questions that assesses HRQL which addresses coping, concern, sleep and social interaction where the scoring scale is from 0 to 100 with a higher score indicating a better quality of life.

SECONDARY outcome

Timeframe: From baseline through 12 Weeks of Intervention

Population: In Group 1, we were unable to analyze 5 patients and in Group 2 we were unable to analyze 3 patients. These participants left for reasons identified in the Participant Flow.

Assessment measured using the Patient Global Impression of Improvement (PGI-I), patient perception of improvement. The PGI-I is a transition scale that is a single question asking the patient to rate their urinary tract condition now, as compared with how it was prior to before beginning treatment on a scale from 1 being very much better to 7 being very much worse. Frequencies of each response was reported. Each level achieved (movement towards 1), is considered an improvement.

SECONDARY outcome

Timeframe: From baseline through 12 Weeks of Intervention

Population: In Group 1, we were unable to analyze 5 patients and in Group 2 we were unable to analyze 3 patients. For this outcome ONLY, 1 patient from each Group were not available to obtain the measurements from this questionnaire. Therefore the overall number of participants analyzed for this outcome is less than other outcomes. Please see Participant Flow.

This was measured using the Patient Satisfaction Questionnaire (PSQ). The PSQ consists of a single question, "How satisfied are you with your progress since your treatment" in which the 3 possible responses are "completely satisfied," "somewhat satisfied," and "not satisfied." The goal of treatment was to move all participants to "completely satisfied.

SECONDARY outcome

Timeframe: From baseline through 12 weeks of Intervention

Population: 25 patients in each group completed voiding diary at baseline. 21 patients completed the voiding diary at 12 weeks in the Tolterodine group (complete diary). 25 patients in the estradiol group completed diary at 12 weeks. Incomplete diaries were not included in our analysis.

Number of voids and accidents/leakage per 3 day diary. A void is a voluntary and intentional event. An accident is involuntary and unintentional.
