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

The H19 gene is a paternally imprinted gene located on chromosome 11p15.5. In this study the H19FR haplotype polymorphism including three SNPs upstream of the H19 gene was investigated. Six genotypes derived from three alleles were detected in the Japanese population by means of PCR and subsequent constant denaturing gel electrophoresis. Based on the methylation status of the genomic DNA from blood samples, selective detection of the parental allele for H19FR was examined by using two types of enzyme, the methylation-sensitive restriction enzymes HpaII or HhaI and McrBC. Genomic DNA digested by either HpaII or HhaI, revealed a single band derived from the paternal allele, as a result of cleavage of unmethylated recognition sites on the maternal allele. On the contrary, the use of McrBC, which can digest a methylated paternal sequence, resulted in exclusively amplifying the maternal allele. This method could be one of the useful techniques for discriminating the parental origin of alleles.
