Abstract
Background
Understanding ulcerative colitis (UC) disease activity assessed via the full, modified or partial Mayo Score may help clinicians apply results from clinical trials to practice and facilitate interpretation of recent and older studies.
Methods
Mayo Score variables were assessed in a cross-sectional study of 2608 UC patients.
Results
Permutations of Mayo Scores were highly correlated, and models predicting the omitted variable from each permutation demonstrated significant agreement between predicted and observed values.
Conclusions
Partial/modified Mayo Scores may be used to predict endoscopic and Physician's Global Assessment scores, and serve as proxies for the full Mayo Score in clinical practice/trials.
