Utilization of a natural language processing-based approach to determine the composition of artifact residues.
Article in BMC bioinformatics, 2024. 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
backgroundDetermining the composition of artifact residues is a central problem in ancient residue metabolomics. This is done by comparing mass spectral features in common with an experimental artifact and an ancient artifact (standard method). While this method is simple and straightforward, we sought to increase the accuracy of predicting which plant species had been used in which artifacts.
resultsHere, we introduce an algorithm (new method) based on ideas from the field of natural language processing (NLP) to solve this problem. We tested our strategy on a set of modern clay pipes. To limit biases, we were not provided information on which plant species had been smoked in which clay pipes. The results indicate that our new method performed 12.5% better than the standard method in predicting the plant species smoked in each artifact.
conclusionsUtilizing an NLP-based approach, we developed a robust algorithm for characterizing the composition of artifact residues. This work also discusses other general applications in which our algorithm could be used in the field of metabolomics, such as datasets where there are a limited number of replicates.
