1 · What the graph read from it

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.

2 · The registry

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

Background: Lassa fever is a zoonotic disease, caused by Lassa virus (LASV), that was first reported in 1965. After 55 years, its research landscape remains largely underexplored. Therefore, a bibliometric study is needed to identify LASV research landscape. Methods: Scopus database was searched and the resulting data was analyzed using VOSviewer (version 1.6.15) for Windows, bibliometrix (version 3.0.0) with Biblioshiny, and R (version 4.5.2) to reveal trends in LASV publications, including keywords, authors' productivity over time, and collaboration among research institutions and universities. Results: From Scopus, 1566 studies were retrieved, and the trend analysis indicated three distinct phases: a low productivity phase (1970-2002), consistent increase phase (2003-2014), and high productivity phase (2015-2025). Conclusion: Despite significant growth in LASV research, critical gaps in vaccines, therapeutics, and endemic region representation highlight the urgent need for locally driven One Health studies and equitable research partnerships.
