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
In cultivated barley (Hordeum vulgare ssp. vulgare), six-rowed spikes produce three times as many seeds per spike as do two-rowed spikes. The determinant of this trait is the Mendelian gene vrs1, located on chromosome 2H, which is syntenous with rice (Oryza sativa) chromosomes 4 and 7. We exploited barley-rice micro-synteny to increase marker density in the vrs1 region as a prelude to its map-based cloning. The rice genomic sequence, covering a 980 kb contig, identified barley ESTs linked to vrs1. A high level of conservation of gene sequence was obtained between barley chromosome 2H and rice chromosome 4. A total of 22 EST-based STS markers were placed within the target region, and the linear order of these markers in barley and rice was identical. The genetic window containing vrs1 was narrowed from 0.5 to 0.06 cM, which facilitated covering the vrs1 region by a 518 kb barley BAC contig. An analysis of the contig sequence revealed that a rice Vrs1 orthologue is present on chromosome 7, suggesting a transposition of the chromosomal segment containing Vrs1 within barley chromosome 2H. The breakdown of micro-collinearity illustrates the limitations of synteny cloning, and stresses the importance of implementing genomic studies directly in the target species.
