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

Primula kwangtungensis, a perennial herbaceous plant endemic to the Nanling Mountains in southern China, is rare and sparsely distributed, making it a conservation priority. This study reports a high-quality chromosome-level genome assembly of approximately 1.29 Gb, achieved through BGI-DIPSEQ, Nanopore, and Hi-C sequencing. Hi-C data anchored 88.68% of contigs to nine chromosomes, with contig N50 of 5.87 Mb and scaffold N50 of 144.82 Mb. The assembly achieved a BUSCO completeness score of 95.8%, indicating high accuracy. A total of 31,717 protein-coding genes were identified, with 97.46% functionally annotated, and repetitive sequences accounted for 63.25% of the genome. This assembly provides crucial data for understanding species diversity mechanisms in the Nanling region and the comparative genomics studies among Primulaceae. It offers essential genetic resources for biodiversity research and aids in developing conservation strategies for rare and endangered plant species.
