A Review of Research Studies Using Data from the Administrative Claims Databases in Japan.
Review in Drugs - real world outcomes, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 17 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
backgroundIn Japan, several research studies have used administrative claims databases. However, no study has compared the studies conducted in each database.
objectiveWe assessed the type, design, and research area of each research study using the administrative databases in Japan to illustrate the suitability of the database used for the types of research studies.
methodsWe reviewed studies from four administrative claims databases (the Japanese National Database of Health Insurance Claims and Specific Health Checkups [NDB]; the DPC Study Group database [DPC]; Japan Medical Data Center [JMDC]; and Medical Data Vision [MDV]). The PubMed database was searched from January 2015 to October 2020. We assessed the type, design, and research area of the abstract or full text of each research study.
resultsOverall, 643 studies were included. The number of studies increased from 59 in 2015 to 171 in 2020. Descriptive studies accounted for 62.7% (42 studies) of the studies from the NDB, while the treatment effectiveness studies accounted for 81.7% (211 studies) of the studies from the DPC database and were the most common in the JMDC and MDV. Cohort studies accounted for only 17.9% of the studies on NDB but 45.5% on DPC. The most common research area was medicine, general, and internal medicine (53 studies, 8.4%).
conclusionsThe type and design of the studies conducted differed in each database and were influenced by the characteristics of the database used. In the future, it may be necessary to integrate various real-world data databases to increase their comprehensiveness.
