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

This study reported the first telomere-to-telomere (T2T) genome assembly of Castanopsis orthacantha, a keystone tree species with significant ecological and economic values endemic to the subtropical evergreen forests of southwestern China. Using multi-platform sequencing data and high-throughput chromosome conformation capture (Hi-C) scaffolding, we successfully generated a chromosome-scale assembly. The final assembly spanned 893.28 Mb, with a contig N50 of 76.19 Mb, indicating a high degree of continuity. Remarkably, 97.94% of the genome was successfully anchored to 12 chromosomes. Terminal telomeric repeat sequences were identified at both ends of all of the chromosomes, and the assembly contained only a single unresolved gap. A total of 35,978 protein-coding genes were detected in the assembly, with an average coding sequence (CDS) length of 1,116.3 bp. Genomic analysis further revealed that repetitive elements comprised 59.28% of the genome. The generation of this near-complete reference genome of C. orthacantha provides a critical genomic resource for advancing evolutionary study within the Fagaceae family and supports conservation genomics strategies aimed at the ecological restoration of this species.
