1 · What the graph read from it

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.

2 · The registry

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

backgroundChamaerops humilis L. is the only endemic palm species of the western Mediterranean. Here, we present a de novo genome assembly with structural and functional annotation that reveals major structural changes shaping the evolutionary history of this species.

resultsThe genome, estimated at 3.44 Gbp, comprises 41,738 genes and 2.87 Gbp of repetitive elements. Evolutionary analyses identified a whole-genome duplication event ~ 48.0 Mya, shared with other palms, followed by divergence from its sister genus Phoenix ~ 16.6 Mya. Functional enrichment of rapidly evolving genes highlighted associations with genome plasticity and stress response pathways. Analyses of gene duplication types and KS distributions uncovered recent lineage-specific duplication waves and C. humilis-exclusive duplicated genes, providing novel insights into palm genome evolution and the adaptive potential of this Mediterranean endemic.

conclusionsThis study provides a high-quality reference genome for C. humilis and insights into the possible genomic basis for Mediterranean adaptation. Future work combining comparative genomics, pangenomics, and functional studies will be key to fully understanding its evolution.
