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
Comparative genomic analysis at the genetic-map level has shown extensive conservation of the gene order between the different grass genomes in many chromosomal regions. However, little is known about the gene organization in grass genomes at the microlevel. Comparison of gene-coding regions between maize, rice, and sorghum showed that the distance between the genes is correlated with the genome size. We have investigated the microcolinearity at Lrk gene loci in the genomes of four grass species: wheat, barley, maize, and rice. The Lrk genes, which encode receptor-like kinases, were found to be consistently associated with another type of receptor-like kinase (Tak) on chromosome groups 1 and 3 in Triticeae and on chromosomes homoeologous to Triticeae group 3 in the other grass genomes. On Triticeae chromosome group 1, Tak and Lrk together with genes putatively encoding NBS/LRR proteins form a cluster of genes possibly involved in signal transduction. Comparison of the gene composition at orthologous Lrk loci in wheat, barley, and rice revealed a maximal gene density of one gene per 4-5 kb, very similar to the gene density in Arabidopsis thaliana. We conclude that small and large grass genomes contain regions that are highly enriched in genes with very little or no repetitive DNA. The comparison of the gene organization suggested various genome rearrangements during the evolution of the different grass species.
