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

Poplar as a diploid and model plant, it possesses abundant genetic diversity and rapid growth characteristics, making it an important species for artificial timber forests. Populus nigra is an important parent in poplar hybrid breeding. With the rapid development of bioinformatics, higher standards of genome analysis are now required. Therefore, haplotype genome assembly of P. nigra is essential for accurately distinguishing homologous chromosomes and for identifying genes associated with significant traits. In this study, we successfully generated a haplotype-resolved near telomere-to-telomere (T2T) chromosome-scale genome and achieved gap-free level of P. nigra. The genome sizes of the two haploid assemblies were 385,184,975 bp and 390,479,648 bp with contig N50 of 22,312,907 bp and 22,054,730 bp, and both had 19 chromosomes. A total of 49,077 and 50,129 genes were annotated for nigraHap1 and nigraHap2. The high-quality assembly in this study not only provides a reference genome for poplar but also could be a foundational basis for research in tree systems biology.
