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

Understanding the genome-wide diversity of jute mallow (Corchorus olitorius L.) is crucial for unlocking the potential of global genebank collections, enabling the discovery and use of traits that support climate resilience, improve nutrition, and increase productivity. Using 23,471 high-quality diversity array technology sequencing single-nucleotide polymorphisms (SNPs), this study assessed the genetic diversity, population structure, and linkage disequilibrium (LD) of 607 accessions. Moderate genetic diversity was detected with a total gene diversity of 0.28, an expected heterozygosity of 0.26, and a Shannon index of 0.42. Four distinct genetic clusters were identified, reflecting geographic patterns, where Cluster 1 (n = 62) and Cluster 4 (n = 354) were predominantly composed of West African accessions. An analysis of molecular variance revealed significant genetic structuring (p < 0.001), with most genetic variation occurring within countries (45.2%), followed by within individuals (32.5%), while differentiation among clusters accounted for 18.2% and variation among regions was minimal (2.9%). LD revealed low genome-wide r
