Development of a High-Resolution Tandem Mass Spectral Library for Pyrrolizidine Alkaloids (PASL).
Article in Scientific data, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
This Data Descriptor reports the submission of a High-Resolution Orbitrap Mass Spectral Library of Pyrrolizidine Alkaloids (PASL) to public repositories. The library contains 165 tandem mass spectra (MS/MS) from 84 pyrrolizidine alkaloid (PA) standards, along with 18 additional PAs manually annotated in crude plant extracts. This collection comprises most commercially available PAs and a unique selection of annotated (in crude extracts) and synthesized compounds. The PASL serves as a valuable resource for identifying PAs in complex mixtures without analytical standards and facilitates the annotation of novel PAs through molecular networking approach. To ensure high quality, the library was validated by dereplicating its spectra against the GNPS libraries and applying it to the annotation of two PA-producing plant species. The spectra of the PASL can be accessed through GNPS ( https://gnps.ucsd.edu/ProteoSAFe/gnpslibrary.jsp?library=PYRROLIZIDINE-ALKALOID-SPECTRAL-LIBRARY ), with accession numbers ranging from CCMSLIB00014205782 to CCMSLIB00014205946 . The PASL in .mgf format can be downloaded from GNPS under: https://external.gnps2.org/gnpslibrary . The PASL enables rapid and straightforward annotation of both known and novel PAs, accelerating research in food safety and related fields.
