Data from: Bristol stool scale: Patient versus expert score data

The Bristol Stool Scale (BSS) is one of the most commonly used tools for
evaluation of stool consistency. BSS ranges from 1-7 and each score is
assigned to a given consistency of the feces. Self-reported
characterizations can differ from an expert evaluation, and the
reliability of BSS is unclear. The dataset consists of BSS scores by
patients with inflammatory bowel disease collected throughout a 3-year
follow-up, matched with scores assessed by experienced bioengineers
(experts). The purpose of the study where data was collected was to
compare patient scores to expert scores and hence determine the
reliability of the BSS.
