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

Haplotypes of polyploid organisms provide important insights into polyploid evolution and advanced breeding strategies. Significant challenges remain in polyploid haplotype phasing, including the great number of haplotype copies and the presence of haplotypes with high local sequence similarity. We present nTChap, a new reference-based polyploid phasing algorithm for long reads, which applies an iterative procedure involving a two-round clustering and consensus construction to generate accurate haplotypes. Using simulated datasets, we show that nTChap outperforms current tools in terms of accuracy and error rates, while maintaining robust performance across high-ploidy genomes and low-coverage data. We then show that nTChap assembles reasonable haplotype structures using real datasets.
