Quantitative analysis of the comprehensiveness and granularity of biomedical terminology systems.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Modern healthcare interoperability demands objective methods for quantitatively evaluating the coverage and granularity of biomedical terminology systems to support evidence-based selection and integration decisions. We introduce novel metrics-structural size (an integrated measure of width and depth), mapping burden ratio (a measure of relative granularity between systems), and content overlap-to quantitatively evaluate the semantic integration potentials of five major terminology systems: SNOMED CT; Logical Observation Identifiers Names and Codes (LOINC); International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM); Gene Ontology (GO); and Current Procedural Terminology. The Unified Medical Language System Metathesaurus was employed to establish semantic equivalency between concepts from different systems. SNOMED CT exhibited superior granularity across most clinical domains, with some exceptions (ICD-10-CM in "Qualifier value," GO in "Observable entity," and LOINC in "Staging and scales.") These findings address the challenge of semantic degradation in health information exchange by quantifying the degree to which meaning might be lost when translating between terminology systems. The proposed metrics empower healthcare organizations to develop targeted extensions or integration strategies that maintain semantic consistency across systems, providing objective tools for terminology system selection, integration planning, and semantic interoperability assessment.
