International overview on juvenile-, adult- and elderly-onset rheumatoid arthritis: The age at disease onset as a fundamental determinant of clinical presentation.

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
backgroundElderly-onset rheumatoid arthritis (EORA) may have peculiar findings compared to juvenile-onset RA (JORA). The aim of the work was to present and compare the clinical characteristics of RA patients with JORA and elderly-onset EORA to a group of cases with adult-onset (AORA) and to contrast the findings worldwide.
methodsThe study included 1100 adult RA patients: 209 JORA and 329 EORA, compared with 562 AORA extracted from a big data national study on 10,364 RA patients. Clinical characteristics, laboratory investigations, medications received, and co-morbidities were recorded. The disease activity index (DAS28) and health assessment questionnaire (HAQ) were estimated.
resultsThe JORA cases represented 19% and EORA 29.9% of the included cohort. The mean age at onset for JORA, EORA, and AORA were 15.1 ± 2.1, 64 ± 4.2, and 36.4 ± 10 years (p < 0.0001), and the female-male ratio was 6.2:1, 2.7:1, and 7.3:1 (p < 0.0001), respectively. In EORA, body mass index (28.8 ± 5.8) and frequencies of smokers (11.6%), diabetes (12.2%), hypertension (19.8%), and osteoporosis (5.2%) were significantly higher than in JORA (26.02 ± 5; 5.3%, 2.9%, 3.8%, and 1%) and AORA (27.6 ± 5.6; 3%, 8.4%, 14.9%, and 2.3%, p = 0.016) (p < 0.0001, p = 0.001, p < 0.0001, and p = 0.009, respectively). In JORA, oral ulcers were significantly more frequent (p = 0.04); in EORA, cardiovascular manifestations (p < 0.0001) and hypothyroidism (p = 0.039) were more frequent; and DAS28 (p = 0.01) and HAQ (p = 0.038) were higher. Fibromyalgia and methotrexate administration were significantly more frequent in AORA (p < 0.0001 and p = 0.04, respectively). Rheumatoid factor, anti-cyclic citrullinated peptide, and double seropositivity were significantly more frequent in EORA (p < 0.0001, p = 0.008, and p = 0.002, respectively).
conclusionComorbidities, cardiovascular manifestations, hypothyroidism, higher disease activity, and functional disability are more common in EORA patients. Key Points • Juvenile-onset and elderly-onset RA patients have notable differences compared to the adult-onset cases. • Co-morbidities and certain manifestations, including cardiovascular disease and hypothyroidism, as well as higher disease activity and functional disability, are more common in elderly-onset patients. • Fibromyalgia remains more frequent in adult-onset cases.
