Ethnic heterogeneity of juvenile arthritis in the Republic of Sakha (Yakutia) related to a high human leukocyte antigen B27 frequency.

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
backgroundPrevalence of the main rheumatic diseases in the Republic of Sakha (Yakutia) [RS(Y)], one of the regions of the Russian Federation, differs from the other regions of the Russian Federation due to its ethnic and geographic features. Knowledge regarding the prevalence and structure of juvenile idiopathic arthritis (JIA) allows us to shape the work of the pediatric rheumatology service in the region correctly, and optimize the healthcare system and the need for medications.
aimTo describe the epidemiological, demographic, clinical, and laboratory characteristics of children with JIA in the RS(Y) and evaluate the main outcomes.
methodsThis retrospective cohort study assessed all the data from the medical histories of the patients (
resultsThe ethnic prevalence of JIA is higher in Sakha than in Russian children at 110.1 per 100000 children and 69.4 per 100000 children, respectively. The prevalence of JIA among boys and girls in Sakha was similar, unlike in Russians, where the number of girls predominated. The JIA categories were as follows: (1) Systemic arthritis: 3.5%; (2) Oligoarthritis (persistent and extended): 33.8%; (3) Rheumatoid factor (RF) (+) polyarthritis: 0.9%; (4) RF (-) polyarthritis: 14.7%; (5) Enthesitis-related arthritis (ERA): 44%; and (6) Psoriatic arthritis: 3.1%. Prevalence of the ERA category was 4.4 times higher in Sakha children, but the prevalence of systemic arthritis was 2.9 times lower compared to Russians (
conclusionHigher JIA prevalence, male and ERA predominance, related to a higher frequency of HLA B27 are typical in RS(Y). These data might improve the pediatric rheumatology health service.
