An exploratory analysis of SNOMED CT national editions.
Article in Journal of the American Medical Informatics Association : JAMIA, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
objectivesThe objectives of this study were to: (1) explore and analyze the structure and content of 19 SNOMED Clinical Terms (SNOMED CT) national editions; (2) identify overlaps and types of quality issues; and (3) offer recommendations to improve the quality of these national editions. MATERIALS AND
methodsWe used expression constraint language and structured query language to analyze and compare the national editions hosted on the SNOMED International SNOMED CT Browser and the International and Canadian Edition Release Format Two files.
resultsThe 19 national editions authored over 275 000 concepts and over 2.1 million descriptions. Modules were used to organize drug extensions, language translations, patient-friendly descriptions, maps, and subsets. The national editions included 27 languages and dialects reference sets, maps to international, national, and local terminologies, and over 1100 subsets. Since 2012, over 28 000 extensions have been promoted to the International Edition. Overlaps were also identified between national editions. DISCUSSION: Challenges of extensions included inconsistent modeling of concepts and quality issues, versioning and maintenance, and risks to semantic interoperability and data analysis. We suggest improved functionality in authoring tools to identify overlapping content across national editions and the incorporation of auditing methods to ensure high-quality extensions, increased collaboration between countries, and the accelerated harmonization of extensions into the International Edition.
conclusionNineteen countries have developed over 2.4 million extension concepts and descriptions, and it is important to harmonize the national editions through ongoing collaboration to maintain the integrity and consistency of SNOMED CT as a global reference terminology.
