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
key messageQSes-7AL is the first major QTL for sharp eyespot resistance identified on wheat chromosome 7AL. The putative candidate gene TaPrx1L-7A was identified and preliminarily validated through integrated multi-omics data and molecular biology approaches. Wheat sharp eyespot is a soilborne disease caused by the necrotrophic fungal pathogen Rhizoctonia cerealis and is a major threat to wheat yield and quality worldwide. In this study, a novel major quantitative trait locus (QTL) for sharp eyespot resistance, designated QSes-7AL, was identified on chromosome 7AL (496.041-499.622 Mb) though analysis of a recombinant inbred line (RIL) population derived from a cross between H63-4 and Yangmai 158, using bulked segregant analysis (BSA), the wheat 660K SNP array, simple sequence repeat (SSR) markers, and kompetitive allele-specific PCR (KASP) markers. A peroxidase-encoding gene, TaPrx1L-7A, was identified as the most likely candidate gene for QSes-7AL based on integrated multi-omics data, gene function annotation, and expression pattern analysis. In addition, the gene was further validated as a strong candidate for QSes-7AL through diagnostic molecular marker, barley stripe mosaic virus-induced gene silencing (BSMV-VIGS), analysis of defense-related gene expression, and measurement of physiological indicators. Overall, these findings provide new insights into the molecular mechanisms underlying wheat resistance to sharp eyespot and offer a theoretical foundation for breeding resistant wheat varieties.
