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

Developing early-maturing maize varieties with improved tolerance to high-density planting is essential for enhancing yield in China. In this study, a unique panel of 498 cold-adapted early-maturing inbred lines were evaluated for ear length (EL) and ear diameter (ED) across two locations under contrasting planting densities in one growing season. Phenotypic analysis revealed abundant phenotypic variation in these ear traits among the tested lines, and there were significant correlations between environments. A total of 406,897 high-quality single nucleotide polymorphism markers (SNPs) were obtained from liquid chip analysis. Population structure analysis classified the early-maturing maize germplasm into 9 distinct genetic groups, with obvious genetic differentiation between groups. Linkage disequilibrium (LD) analysis demonstrated rapid LD decay and high genetic variation in the population. A genome-wide association study (GWAS) identified 380 quantitative trait loci (QTLs) for both ED and EL under two planting densities. In total, 138 and 89 annotated genes were identified within QTLs detected under normal and high-density planting conditions, respectively. Among them,
