Global Functioning in Axial Spondyloarthritis is Stronger Associated With Disease Activity and Function Than With Mobility and Radiographic Damage.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveThe Assessment of Spondyloarthritis International Society Health Index (ASAS HI) is a validated patient-reported outcome (PRO) for global functioning of patients with axial spondyloarthritis (axSpA). The Epionics SPINE (ES) is an electronic device for assessment of axial mobility that provides an objective measure of spinal mobility by assessing range of motion (RoM) and range of kinematics (RoK). The aim of this study is to investigate the relationship between global functioning and clinical measures of disease activity, physical function, spinal mobility, and radiographic damage.
methodsIn a cross-sectional study design, consecutive patients with radiographic and nonradiographic axSpA were included, and the following established tools were assessed: Bath ankylosing spondylitis (AS) disease activity index (BASDAI), Bath AS functional index (BASFI), Bath AS metrology index (BASMI), ASAS HI, and RoM and RoK using ES. Structural damage of spine and sacroiliac joints (SIJ) were assessed by counting the number of syndesmophytes and by New York grading of sacroiliitis. Kendall's tau correlation coefficients were calculated.
resultsIn 103 patients with axSpA, ASAS HI scores correlated significantly with PRO scores (BASDAI, r = 0.36; BASFI, r = 0.48; and back pain, r = 0.41; all P < 0.001). In contrast, no significant correlation between ASAS HI and RoM and RoK (r between -0.08 and 0.09) and radiographic damage in SIJ and spine (all r between 0.03 and 0.004) were seen, respectively. BASMI scores correlated weakly (r = 0.14; P = 0.05).
conclusionThis study shows that axSpA disease-specific PROs have an impact on global functioning, whereas spinal mobility scores, even if objectively assessed by the ES, have limited impact on patient reported-global functioning. The results also suggest that global functioning is, in this cohort, not much dependent on the degree of structural damage in the axial skeleton.
