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
Imprinted genes are preferentially expressed from either the maternally inherited allele or the paternally inherited allele. Most genes known to be imprinted have been identified and studied in the human and the mouse. There is only a small number of reported imprinted genes in cattle, which is probably because of the limited sequence and polymorphism information available for bovine genes. To study the imprinting status of cattle genes and assess their conservation among mammalian species, the expression patterns of COPG2, DCN, and SDHD genes were examined in a total of 128 fetal and adult tissues. Two single nucleotide polymorphisms (SNPs) were identified in COPG2, three SNPs in DCN, and one SNP in SDHD. These polymorphisms were used to distinguish between monoallelic and biallelic expression using a primer extension method and a sequencing-based approach. In all 128 tissues, COPG2, DCN, and SDHD transcripts showed biallelic expression. Other cattle genes examined to date have been found to be imprinted like their known counterparts in human and mouse. This is the first report of genes that are not imprinted in cattle while the corresponding genes in human or mouse are imprinted. Lack of conservation of imprinting among mammals suggests important biological, developmental, and regulatory consequences.
