Prevalence, characteristics, and screening of spondyloarthritis in Japanese patients with early inflammatory bowel diseases: a prospective multidisciplinary study.

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
backgroundThe prevalence and characteristics of inflammatory bowel disease-associated spondyloarthritis (IBD-SpA) in Japan are unclear. Moreover, methods for screening SpA among IBD patients have not been established.
methodsThis single-center prospective multidisciplinary study included consecutive patients with IBD, which was newly diagnosed within the past 3 years (early IBD). Board-certified rheumatologists examined the patients for disease history and musculoskeletal manifestations, with imaging studies if needed. Questionnaires assessed patient-reported outcomes and Psoriatic Arthritis Screening and Evaluation (PASE) scores.
resultsWe identified 85 eligible patients with early IBD, 22 (25.9%) of whom had Crohn's disease, 63 (74.1%) had ulcerative colitis, and 3 (3.5%) had IBD-SpA diagnosed prior to study enrollment. Rheumatologist evaluations identified additional seven SpA cases, resulting in a total of 10 patients (11.8%) with IBD-SpA (1: axial, 9: peripheral). IBD patients without SpA often presented with back pain (52%) and peripheral joint pain (24%), whereas arthritis, cervical and thoracic pain, and inflammatory back pain were more frequent in IBD-SpA. Newly identified IBD-SpA cases tended to have lower-limb arthritis, dactylitis, and enthesitis, compared with previously diagnosed IBD-SpA cases. For patients with active SpA symptoms in the past 6 months, PASE demonstrated that the area under the receiver operating characteristic curve was 0.87 (95% confidence interval: 0.68, 1.00). The optimal cut-off (33 points) had a sensitivity of 0.88 and specificity of 0.88.
conclusionsThis prospective study found rheumatologist evaluation increased SpA diagnosis and 11.8% of Japanese early IBD patients had IBD-SpA. PASE questionnaires may be effective for screening SpA among IBD patients.
