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

Ferns are an ancient lineage of vascular plants, yet limited genomic resources constrain both evolutionary and conservation inference. Here, we generate a chromosome-level genome assembly for the endangered cycad fern Brainea insignis (8.62 Gb), the sole species in its genus within eupolypods II, and integrate comparative and population genomics to resolve its evolutionary history and vulnerability. The genome retains the ancient whole-genome duplication shared by leptosporangiate ferns; however, its exceptional size is driven primarily by recent repeat accumulation and further shaped by lineage-specific evolutionary signatures linked to functional specialization. Resequencing across the range identifies three geographically and environmentally structured lineages shaped by Quaternary refugia, limited postglacial expansion and localized admixture. Recently reduced populations show pronounced genomic erosion, including inbreeding and elevated genetic load, due to insufficient time for purging. We detect climate-associated local adaptation and project substantial future genetic offsets, with southwestern Indochina populations at highest risk. Our results expand fern genomics and support spatially tailored conservation strategies that maintains habitat connectivity and promotes adaptive gene flow.
