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

Colusa grass, Neostapfia colusana, is a listed California endangered plant endemic to the vernal pools of California. Vernal pool habitat is highly degraded and threatened by further anthropological development, with only 10% of its historical range remaining. With only 42 confirmed extant populations, it is a major conservation concern to understand patterns of genomic diversity. Here we report the first complete genome assembly of Colusa grass. The assembly includes two haplotypes: haplotype one spans 2.13 Gb with contig N50 of 10.62 Mb, scaffold N50 of 112.31 Mb, and BUSCO completeness of 98.1%. Haplotype two spans 2.04 Gb with contig N50 of 10.05 Mb and scaffold N50 of 138.31 Mb, with a BUSCO completeness of 97.6%. This genome assembly will allow for in-depth analysis of genomic variation and gene flow in populations of this threatened grass and will be a major asset to studies supporting its conservation. This genome was assembled as part of the California Conservation Genomics Project, which contributes to a collection of resources and tools to support state-wide conservation efforts.
