Does the UCEIS provide better predictive value for clinical remission than the Mayo Endoscopic Score in patients with moderate disease

What is known

- UCEIS is reported to reflect clinical outcomes and long-term prognosis more accurately than the Mayo endoscopic score, including predicting response to immunomodulators/biologics and need for colectomy. ^1,2 - In one cohort, both DUBLIN and UCEIS showed better application potential than the Mayo score for reflecting disease activity and predicting clinical response and outcomes. ¹ - UCEIS uses vascular pattern, bleeding, and erosions/ulcers on a 0–8 scale, giving finer severity distinctions than the four-grade Mayo score. ¹

What is unknown / caveats

- No excerpt isolates predictive value for clinical remission in moderate-disease patients specifically - Moderate-severity comparison reported here concerns score distributions, not remission prediction - The moderate-disease finding available is that Mayo scores did not differ between moderate and severe patients while UCEIS did not differ between mild and moderate patients ¹, which speaks to discrimination, not remission prediction.
