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

Mutation of primer site for genotyping by polymerase chain reaction (PCR) may cause allele dropout and other genotyping failures. Primary hyperoxaluria type 2 (PH2) is a rare inherited disease caused by overproduction of endogenous oxalate due to mutations in the glyoxylate/hydroxypyruvate reductase (GRHPR) gene. Here, to avoid allele dropout and primer annealing to multiple sites, and given the discrepancy in intron length between GRHPR gene data, we updated the primers used in the sequence assay of the GRHPR gene. These redesigned primers show potential in reducing detection failure of GRHPR mutations. In addition, we performed a single nucleotide polymorphism (SNP) linkage analysis of the GRHPR gene using direct sequencing with PCR amplification of specific alleles (DS-PASA). Using this technique, we sequenced four common SNPs between intron E and exon 6, which show linkage disequilibrium (LD) consisting of three types of haplotypes, similar to data from the HapMap SNP database.
