Development of a data dictionary on viral hepatitis for the Philippines.
Article in Oxford open digital health, 2024. 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
The considerable difference between the reported number of actual and estimated viral hepatitis cases in the Philippines can be attributed to the lack of reliable data. Since viral hepatitis is endemic in the country, efficient disease control depends on access to quality data. The rapid adoption of electronic medical records in different facilities in the country offers opportunities for access to such data but raises concerns about its standardization for analysis. This study presents the steps taken toward the adoption of a standardized data dictionary for viral hepatitis, referencing existing international terminology standards. A series of workshops were conducted to gain consensus among subject matter experts such as epidemiologists, hepatologists and informaticists. These workshops provided context to the different stakeholders through a shared understanding of viral hepatitis care processes and transforming these into computable representations. Using Department of Health-approved paper forms for viral hepatitis surveillance, a multidisciplinary team mapped the 125 unique data elements to various international standard code sets. The output was a draft Philippine Viral Hepatitis Data Dictionary-a prerequisite for the semantic interoperability of data from different electronic medical records.
