A new approach to defining functional ability in ankylosing spondylitis: the development of the Bath ankylosing spondylitis functional index
Abstract
The clinical assessment of disease activity in patients with AS is often not easy. A few functional indices have now been developed for longitudinal follow-up of AS patients, and for monitoring their response to therapy. The most widely used measures of functional capacity in AS is the Bath ankylosing spondylitis functional index (BASFI) (score 0-10). Disease activity has been assessed by using a self-administered composite index called the Bath ankylosing spondylitis disease activity index (BASDAI) that consists of an evaluation on a visual analogue scale (from 0-10) focusing on axial pain, peripheral joint pain, fatigue/tiredness, enthesitis, and morning stiffness). BASDAI has been found to be a valid and appropriate composite to define disease activity in AS.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
