Ulcerative Colitis Models Show Moderate Predictive Performance
6.0
A systematic review and meta-analysis up to November 2, 2024, evaluated 30 studies of prognostic models for ulcerative colitis involving 7,452 patients. The pooled area under the curve was 0.84 (95% CI 0.77–0.92), but 29 of 30 studies had high risk of bias and only 14 included external validation, limiting generalizability.
Key Points
- 1Identify 30 prognostic models across 7,452 UC patients; pooled AUC equals 0.84.
- 2Highlight high risk of bias in 29 of 30 studies, notably in selection and analysis.
- 3Recommend multicenter external validation and improved development practices for broader clinical applicability.
Scoring Rationale
Comprehensive meta-analysis and pooled AUC indicate utility, but pervasive bias and scarce external validation limit practical impact.
