The performances of the ILAR, ASAS, and PRINTO classification criteria in ERA patients: a comparison study.
Article in Clinical rheumatology, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers, 1 of them a synthesis that pooled it.
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
backgroundEnthesitis-related arthritis (ERA) could be considered the pediatric equivalent of ankylosing spondylitis in adults albeit with certain significant differences. We aim to evaluate the sensitivity and specificity of the International League of Associations for Rheumatology (ILAR), the Assessment of Spondyloarthritis International Society (ASAS), and the preliminary Pediatric Rheumatology International Trials Organization (PRINTO) classification criteria in ERA patients.
methodThe medical records of ERA patients who were followed up between January 2005 and September 2020 have been analyzed. The control group consisted of patients with oligoarticular JIA (n = 146), polyarticular JIA (n = 55), and psoriatic arthritis (n = 20).
resultsThis retrospective study included 108 ERA (73.1% male) and 221 control patients (25.8% male). The median age at diagnosis for ERA and control patients were 12.5 and 4.0 years, respectively (p < 0.001). Arthritis was observed more frequently in the control group at diagnosis and in the follow-up (p < 0.001 for both), while enthesitis, sacroiliac joint tenderness, and inflammatory back pain were more common in the ERA group both at diagnosis and in the follow-up (p < 0.001 for all). In sacroiliac imaging, 70.1% of ERA patients had positive findings suggestive of sacroiliitis at diagnosis and 78% in the follow-up. The sensitivities of ILAR, PRINTO, ASAS criteria for axial SpA, and peripheral SpA at diagnosis were 74.0%, 57.4%, 21.3%, and 85.1%, respectively which increased to 82.4%, 78.7%, 35.1%, and 92.5%, respectively at follow-up. The specificities were 100%, 100%, 99.1%, and 90.9%, respectively at both diagnosis and follow-up.
conclusionThe ASAS criteria for peripheral SpA were the most sensitive while ILAR and the preliminary PRINTO criteria were the most specific criteria for classifying ERA patients. KEY POINTS: The ASAS criteria for peripheral SpA were the most sensitive criteria for classifying ERA patients. The use of ASAS axial SpA criteria may provide early detection of axial involvement.
