Phytoliths in dicotyledons occurring in Northwest Europe: establishing a baseline.
Article in Annals of botany, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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 AND
aimsThe absence of a modern plant-based 'dicotyledon' phytolith reference baseline impedes the accurate interpretation of fossil phytolith records in archaeological and palaeoecological research within Northwest (NW) Europe. This study aims to fill this gap by documenting and analysing the phytolith record from modern dicotyledon taxa occurring in this region.
methodsPhytoliths were extracted from several plant parts of 117 plant specimens representing 74 species (one or two specimens per species). The study employed light microscopy to examine phytolith production (non-producer, trace, common or abundant) and phytolith assemblage composition. The data were analysed statistically to (1) determine the influence of taxonomy and plant part on phytolith presence (absent/present) using a mixed model, (2) assess phytolith assemblage variation using a permutational multivariate analysis of variance (PerMANOVA) and (3) identify patterns among sample groups including segregation for plant part, life form (forbs vs. shrubs/trees) and order using linear discriminant analyses (LDA). KEY
resultsMorphotype analysis revealed diagnostic morphotypes and features for specific plant families, genera and plant parts. LDA effectively segregated plant parts and life forms, though taxonomic groupings showed limited segregation. Phytolith presence (absent/present) was found to vary, influenced by both plant part and taxonomy. For species examined through two specimens, although phytolith production varied considerably, phytolith assemblage composition was consistent.
conclusionsThis study establishes a 'dicotyledon' phytolith baseline for NW Europe, showing that the phytolith record can be informative in terms of plant part and life form and that several phytolith morphotypes and/or features are taxonomically diagnostic below 'dicotyledon' level. The findings constitute a foundation upon which future research can build, refining and expanding our knowledge of the NW European region.
