Epidemiology of juvenile idiopathic arthritis in Oman.
Article in Pediatric rheumatology online journal, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 16 papers.
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
backgroundThere is a worldwide variation in the prevalence and subtype distribution of juvenile idiopathic arthritis (JIA) which may be affected by ethnicity and genetic factors. The purpose of this study is to determine the prevalence, subtype distribution and characteristic features of JIA among Omani children and to compare our results with other ethnic populations worldwide.
methodsA population-based, multicenter study among pediatric rheumatology clinics in the Sultanate over a 10 year period between 2004-2013. The diagnosis of JIA and identification of JIA subtypes was based on the ILAR 2004 revised criteria. The hospital charts of these patients were retrospectively reviewed and information was collected. All patients were screened for uveitis by an ophthalmologist using slit lamp examination during regular follow up visits.
resultsThe study included a total of 107 cases of JIA in Oman over the study period. Among the 107 patients, 71 % (n = 77) were girls with a female:male ratio of 2.5:1. The mean age of disease onset was 6.85 ± 3.86 years (range 1-13years) while the mean disease duration of 4.8 ± 2.9 years (range 1-11 years). The incidence of JIA was estimated at 2/100,000 with a prevalence of JIA of 20/100,000. The prevalence of JIA in girls was 28/100,000 while the prevalence in boys was 12/100,000. According to disease distribution, the most frequent subtype was polyarticular JIA rheumatoid factor negative (39.2 %) followed by oligoarthritis (31.8 %), systemic (17.8 %), polyarticular JIA rheumatoid factor positive (7.5 %). The unique feature of the Omani cohort is the lack of occurrence of uveitis.
conclusionsThis is the first epidemiological JIA study conducted in Oman that highlights unique geographical disease phenotype. Compared to Western counties, there were higher frequency of polyarticular disease and lack of occurrence of uveitis. Further studies are needed to evaluate the implications of genetic, ethnic and environmental differences of disease expression.
