Profile and Data Quality of DataVerse Japan: A Multi-Institutional Clinical Data Platform for Emergency and Critical Care Research.
Article in Acute medicine & surgery. 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
Aim: DataVerse Japan is a multi-institutional clinical data platform that retains all exportable clinical information from each participating center's information systems and generates analysis-ready datasets for each research question. This study aimed to describe its design, participating centers, data composition, and patient profile, and to characterize its data quality. Methods: The platform captures clinical information from each center's information systems, currently the electronic health record (EHR), which incorporates patient data management system (PDMS) data and claims data; reshapes the records into a common five-column long-format (Code, Day, Time, Variable, Value); and stores them as relationally linked. rds objects. We summarized admissions to the participating centers between January 2016 and December 2025. Results: Four emergency and critical care centers contributed 41,173 admissions from 38,287 individuals and 644,838 patient-days. The platform contains approximately 45 million vital sign records, 30 million laboratory records, and 32 million claims records. Median patient age was 70 years (IQR 49-81), and in-hospital mortality was 16.3%. Admission-level presence coverage, defined as the proportion of admissions with at least one record in a category, varied substantially by category, center, and year and improved after EHR and PDMS upgrades. Conclusion: DataVerse Japan provides a continuously updated multi-institutional clinical data platform that expands its participating centers over time. The coverage and validation metrics reported here allow investigators to judge whether the platform is suitable for a specific research question in emergency and critical care medicine in Japan.
