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

backgroundNeutrophil formylpeptide receptors (FPRs) play an important role in bacterial recognition and chemotaxis. Defective FPR1 expression and impaired polymorphonuclear leukocyte chemotaxis toward bacterial formylpeptides are associated with aggressive periodontitis (AgP). The objective of this study was to determine whether single nucleotide polymorphisms (SNPs) in FPR1 are associated with AgP.

methodsGenomic DNA was isolated from blood samples obtained from African Americans (30 subjects with AgP and 33 healthy controls) and Turks (75 subjects with AgP and 63 healthy controls). A highly polymorphic fragment of the FPR1 gene was amplified by polymerase chain reaction and sequenced for analysis of SNPs.

resultsFive previously identified SNPs were detected in African Americans, whereas six were detected in Turkish subjects. The frequency of synonymous SNP c.348T>C was significantly higher in African Americans with AgP than in controls (P = 0.029). The 348T allele was significantly associated with AgP (P = 0.010). Seven of the subjects with AgP, but none of the controls, were homozygous for 348T. FPR1 haplotypes 348T.568A, 348T.576T, and 348T.568A.576T were significantly increased in African Americans with AgP (P <0.02). The Turkish population did not exhibit significant differences in FPR1 SNP frequencies between subjects with AgP and controls.

conclusionsFPR1 SNP c.348T>C is associated with AgP in African Americans. Individuals who are homozygous for 348T may have an increased risk for developing this disorder.
