The Mollusc Collection (Class Polyplacophora) at the Museum of Zoology, University of Concepción: curation status and value for integrative research.
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: Within a museum of biological collections, the care and periodic updating of collections represent a fundamental pillar of curatorial work. Keeping collections in good condition ensures better access for researchers interested in consulting or studying a specific taxonomic group. At the Museum of Zoology of the University of Concepción, a total of 140 samples belonging to the Polyplacophora class collection were curated. The first digitisation of this collection was carried out under the Darwin Core (DwC) standard, providing full accessibility to the respective collection data available in the GBIF and OBIS biodiversity databases. The collection consists of specimens collected between 1954 and 2022 in a wide range of localities, mainly in Chile and other countries such as Argentina, Ecuador and Norway, covering a total of 19 species. Additionally, in the year 2023, an evaluation of the collection's health status was conducted, revealing that 42.857% of the samples had health levels of 5 or lower, while 57.143% were at level 6. By 2024, 96.429% of the collection improved to a health level of 7, while 3.571% remained at a health level of less than 5. These results indicate that the collection is in ideal conditions, detecting an improvement of the physical and digital material of the mollusc collection. This improvement enables researchers to more easily access information from the validated collection, supporting research in various areas such as conservation, resource management, climate change and biogeography. New information: This study represents the first report evaluating the health index of biological collections in Chile, showing how the prioritisation of actions requiring attention is important for the preservation of natural heritage. It also contributes to the current knowledge of biological collection databases in Chile, promoting the use of digital databases for better management of records and their information, so they can be used in future studies in various fields of natural sciences that require specific data.
