Phenotypic diversity of sorghum [
Article in Heliyon, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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.
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
It is essential to comprehend genetic diversity for the conservation and effective utilization of crop genetic resources. There is limited information on genetic resource collection, phenotypic characterization, and conservation of sorghum genotypes in Ethiopia, particularly in the southern region. The study was conducted at the Jinka Agricultural Research Centre during the 2021 cropping season, to quantify and qualitatively assess the morphological diversity of sorghum genotypes. 225 genotypes were evaluated using a simple lattice design replicated twice. Data on 8 qualitative traits were collected and subjected to the Shannon-Weaver diversity index (H') and multivariate analyses and data on 17 quantitative traits were subjected to multivariate analyses. The estimate of H' ranged from 0.46 for grain color to 0.95 for panicle compactness and shape. Panicle exsertion, midrib color, pericarp color, awns, grain covering, and panicle compactness and shape were the most effective traits for distinguishing among sorghum genotypes. The first three and six principal components explained (59.0 %) and (76.5 %) of the total variation for qualitative and quantitative traits, respectively. A cluster analysis based on qualitative and quantitative traits identified five and four distinct groups, respectively. The highest inter-cluster distance was found between cluster I and V (D
