INKA App Study: Clinical Trial Data for Overactive Bladder Management

A German clinical trial involving 251 patients with therapy-refractory overactive bladder or mixed incontinence, randomized to use the INKA mobile app or receive standard care. The dataset includes self-assessed endpoints measured at baseline, 4 weeks, and 12 weeks, with results published by author L. Schramm. The study was last updated in April 2026.

Use Cases

• Compare micturition frequency changes between intervention and control groups based on reported 24-hour frequency data.
• Analyze quality of life improvements using ICIQ-OABqol questionnaire scores mentioned in the results.
• Assess the impact of digital therapy on urine volume per micturition, a key endpoint reported in the study.
• Investigate subgroup outcomes, such as differences in efficacy between female participants and those with higher symptom severity.

Strengths

• Data originates from a registered, multi-center clinical trial (DRKS ID 00029329) conducted at 35 sites.
• Includes results for 111 evaluable patients with specific baseline demographics (mean age 52.7 years, 73% female).
• Reports quantitative outcomes with standard deviations, such as a mean reduction of -1.02 micturitions per 24h in the intervention group.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The dataset is very small (554.8 KB), indicating limited scope, likely containing summary results rather than raw patient-level data.
