tRNA gene content, structure, and organization in the flowering plant lineage.
Article in Frontiers in plant science, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Transfer RNAs (tRNAs) are noncoding RNAs involved in protein biosynthesis and have noncanonical roles in cellular metabolism, such as RNA silencing and the generation of transposable elements. Extensive tRNA gene duplications, modifications to mature tRNAs, and complex secondary and tertiary structures impede tRNA sequencing. As such, a comparative genomic analysis of complete tRNA sets is an alternative to understanding the evolutionary processes that gave rise to the extant tRNA sets. Although the tRNA gene (tDNA) structure and distribution in prokaryotes and eukaryotes, specifically in vertebrates, yeasts, and flies, are well understood, there is little information regarding plants. A detailed and comprehensive analysis and annotation of tDNAs from the genomes of 44 eudicots, 20 monocots, and five other non-eudicot and non-monocot species belonging to the Ceratophyllaceae and the ANA (Amborellales, Nymphaeales, and Austrobaileyales) clade will provide a global picture of plant tDNA structure and organization. Plant genomes exhibit varying numbers of nuclear tDNAs, with only the monocots showing a strong correlation between nuclear tDNA numbers and genome sizes. In contrast, organellar tDNA numbers varied little among the different lineages. A high degree of tDNA duplication in eudicots was detected, whereby most eudicot nuclear genomes (91%) and only a modest percentage of monocot (65%) and ANA nuclear genomes (25%) contained at least one tDNA cluster.
