The "GfI-Fischartenatlas" of the German Ichthyological Society (GfI) - A compilation of validated fish species occurrence records.
Article in Biodiversity data journal, 2026. 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
Background: Despite the urgent need for conservation, reliable data on the distribution of fish species across countries and federal states is limited for both freshwater and marine habitats. The German Ichthyological Society (Gesellschaft für Ichthyologie e.V. or GfI) aims to compile fish distribution data with a focus on Germany (including its marine areas), Austria and the marine areas of the Netherlands and Denmark. These data are openly available on the "GfI-Fischartenatlas" web portal which serves as an information platform at the intersection of science, practice and environmental education, promoting the conservation of fish biodiversity and their habitats. The GfI-Fischartenatlas is a joint project of the GfI and the City University of Applied Sciences Bremen. It was developed in cooperation between the biology and computer science departments at the university. The IT basis for collecting, managing and presenting the data online is the "Biodiversity Warehouse" software architecture. The data are hosted by the Biodiversity Informatics Department at the Museum Koenig Bonn, which is part of the Leibniz Institute for the Analysis of Biodiversity Change (LIB). New information: The GfI-Fischartenatlas consolidates fish distribution data from various cross-border sources into a unified platform. This includes both data collected specifically for the atlas and data integrated from other databases (in total n = 136,714, as of 13.03.2026). The data primary to the atlas are published as a dataset on the Global Biodiversity Information Facility (GBIF). This dataset (ABCD archive) contains occurrence records (n = 62,545) for 264 freshwater and marine fish species, derived from scientific and grey literature as well as citizen0science observations, covering 16 European countries (with a focus on Germany and Austria).
