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

aimsInherited polymorphisms of codons 16, 27, and 164 of the beta2-adrenergic receptor (B2AR) gene may result in significantly changed functions of this receptor. The aim of the present study was to investigate the frequencies of the main mutations of the B2AR gene in Turks.

methodsA group of 104 unrelated Turkish subjects were analysed for the Arg16Gly, Gln27Glu, and Thr164Leu polymorphisms of B2AR by a newly designed polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay. A 242-bp amplicon including the Arg16Gly and Gln27Glu polymorphisms was generated including an arbitrary restriction site, allowing the cleavage with Eco130I or Fnu4HI for analysis of the two polymorphic sites, respectively. For the amino acid polymorphism at codon 164 a 280-bp fragment was generated and digested by MnlI.

resultsThe allelic frequencies of mutated Gly16, Glu27, and Ile164 alleles were found as 59.6%, 31.7%, and 0.5%, respectively. Although, the frequencies of the polymorphisms at codon 16 and 164 were found similar as in various Caucasian populations, the frequency of the Glu27 variant was found significantly lower than these populations.

conclusionsObviously there are interethnic differences in functionally relevant B2AR variants which may have implications for drug treatment and disease susceptibility.
