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

The California poppy (Eschscholzia californica), a native wildflower of western North America and the state wildflower of California, is characterized by extensive ecological variation and adaptation to diverse climatic conditions. Its broad geographic range and adaptability make it a valuable model for studying how plants respond to changing environmental conditions. Here, we present an updated, near-chromosome-level genome assembly for E. californica, developed as part of the California Conservation Genomics Project. This assembly spans 0.401 Gb and represents an advancement over previous versions, with a scaffold N50 of 66.4 Mb, a contig N50 of 11.8 Mb, and BUSCO completeness of 99.2%, providing near-complete genomic coverage. The enhanced genome assembly described here facilitates precise whole-genome resequencing, providing insights into genetic diversity and gene flow between populations-key factors in understanding the adaptive mechanisms that will support the species' survival in the face of environmental challenges.
