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

Assembling polyploid genomes at the chromosome level remains a major challenge due to the difficulty of accurately distinguishing homologous chromosomes, leaving a vast number of polyploid species without high-quality genome sequences. Current chromatin conformation capture (3C)-based haplotype-resolved scaffolding methods often produce highly incomplete and mis-phased assemblies of complex polyploids, as short sequences lacking sufficient interaction support and collapsed regions with misleading signals are difficult to resolve. Here we present GPhase, a haplotype-resolved scaffolding algorithm that integrates 3C (for example, Hi-C, Pore-C and Omni-C) data with assembly graphs to enhance accuracy, completeness and contiguity. By leveraging graph connectivity derived from long-read overlaps, GPhase effectively overcomes key limitations of 3C. When applied to 15 complex polyploid genomes, GPhase reduced the sequence missing rate (BUSCO-based) by up to tens-fold, decreased the sequence error rate (k-mer-based) by up to an order of magnitude and improved the contiguity (N50) of gap-free sequences by several-fold compared with existing tools.
