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

Hemagglutination-based assays have several clinical shortcomings. To overcome this difficulty, we have developed a multiplex-PCR SNaPshot assay adapted to the Southern French population, which includes individuals from sub-Saharan Africa and the Comoros archipelago. Single nucleotide polymorphisms (SNPs) associated with clinically relevant blood antigens as well as with null phenotypes were profiled (i.e., K/k, Fy(a)/Fy(b)/Fy(bw)/Fy(null), S/s/U-/U+(var), Jk(a)/Jk(b), Do(a)/Do(b), Yt(a)/Yt(b), and Co(a)/Co(b)). A single multiplex-PCR reaction was used to amplify nine gene regions encompassing 11 SNPs. Identification was obtained by incorporation of the complementary dye-conjugated single base at the 3' end of each probe primer annealed proximal to the target SNP. After optimization, the SNaPshot assay was validated with 265 known allele or phenotype pairs. Results were found fully concordant with those of hemagglutination, allele-specific PCR, and/or sequencing. The assay was then evaluated on 227 blood samples in a clinical context. A total of 203 derived-phenotypes were generated, including 82 atypical phenotypes [i.e., Fy(b+(w)) (n = 32); K(+) (n = 22); Co(b+) (n = 8); Yt(b+) (n = 18); S-s+U+(var) (n = 2), 105 null phenotypes, i.e., Fy(a-b-) (n = 97); S-s-U- (n = 6); S-s-U+(var) (n = 2)] and sixteen Fy-positive samples carried a FY*Fy allele. The findings show that this assay can provide a low-cost and fast genotyping tool well adapted to local ethnically mixed populations.
