Contribution to the DNA barcode reference library for Réunion Pteridophyta.
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: Expanding DNA barcode reference libraries is essential to support ecological surveys, conservation assessments and future metabarcoding applications. Réunion Island (Mascarene's Archipelago) hosts a rich diversity of pteridophytes despite its small surface area. Although the chloroplastic rbcL sequences are available for several fern taxa in public databases, additional regions with high variability such as trnH-psbA are still under-represented for the Réunion pteridoflora. This dataset has been produced in the framework of the FRBOL (FRench Barcode Of Life) network. New information: The current curated DNA barcode dataset contains 84 pteridophyte species from Réunion Island, representing approximately 25% of the pteridophyte species present on the Island. All specimens were morphologically identified by a specialist and are preserved as vouchers in the public herbarium of the University of Réunion (REU). A total of 163 sequences of rbcLa (86) and trnH-psbA (77) were generated and deposited in the Barcode of Life Data System (BOLD) with complete associated metadata and photos. While numerous rbcLa sequences were already available on GenBank, our dataset provides newlygenerated sequences linked to curated vouchers on BOLD and substantially increases the representation of trnH-psbA for the Island's pteridophytes. Additionally, this work documents the first record of
