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 messageGenetic analysis and genome mapping of a major seedling oat crown rust resistance gene, designated PcKM, are described. The chromosomal location of the PcKM gene was identified and linked markers were validated. Crown rust (Puccinia coronata Corda f. sp. avenae Eriks) is the most important foliar disease of oats and can cause considerable yield loss in the absence of appropriate management practices. Utilization of novel resistant genes is the most effective, economic and environmentally sound approach to control the disease. Crown rust resistance present in the cultivar 'Morton' was evaluated in a population developed from the cross OT3019 × 'Morton' to elucidate the genetic basis of resistance. Crown rust reaction evaluated in field nurseries and greenhouse tests demonstrated that resistance provided by 'Morton' was controlled by a single gene, temporarily designated as PcKM. The gene was initially linked to a random amplified polymorphic DNA band and subsequently converted into a sequence characterized amplified region (SCAR) marker. Genotyping with the PcKM SCAR on the 'Kanota' × 'Ogle' population, used to create the first oat chromosome-anchored linkage map, placed the PcKM gene on chromosome 12D. Consensus map markers present in the same region as the PcKM SCAR were tested on the OT3019 × 'Morton' population and two additional phenotyped populations segregating for PcKM to identify other markers useful for marker-assisted selection. Three markers were perfectly linked to the PcKM phenotype from which TaqMan and KBioscience competitive allele-specific PCR assays were developed and validated on a set of 25 oat lines. The assays correctly identified PcKM carriers. The markers developed in this study will facilitate fine mapping of the PcKM gene and simplify selection for this crown rust resistance.
