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

backgroundIdeal plant architecture is central to high-yield maize breeding. The proportional length of internodes above the ear plays a crucial role in determining plant architecture.

methodsIn this study, we used an association panel comprising 288 maize inbred lines and performed genome-wide association studies (GWASs) with 1.25 M high-density single nucleotide polymorphism (SNP) markers under a Q + K mixed linear model.

resultsA total of 821 significant SNPs associated with plant height (PH), height above ear (HAE), and internode-related traits were detected, which were further classified into 417 quantitative trait loci (QTL). Among these, 128 significant SNPs and 44 QTL were identified for the U1/HAE trait, and 37 significant SNPs and 27 QTL for the U1/PH trait. Four stable QTL (

conclusionsThese findings provide new genetic insights into the regulation of maize internode proportion and plant architecture, offering potential targets for molecular breeding.
