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

BACKGROUND AND

objectivesThe para-Bombay phenotype is characterized by H antigen deficiency and the natural production of antibody against the I and H antigens (anti-IH), some of which are occasionally clinically significant. It genetically results from the presence of two non-functional FUT1 alleles coupled with at least one functional FUT2 allele. We present the serological and molecular characterization of a para-Bombay phenotype case, which led to the identification of a novel FUT1 allele. MATERIALS AND

methodsA sample from a blood donor was identified as a result of a discrepancy between forward and reverse typing. This sample subsequently underwent serological typing for A, B and H antigens in accordance with the American Association of Blood Banks Technical Manual. Furthermore, Sanger sequencing and nanopore sequencing were employed to analyse the ABO, FUT1 and FUT2 genes.

resultsThe donor was found to have an H-deficient phenotype and the presence of anti-IH. Sanger sequencing identified an ABO*A1.01/ABO*O.01.02 genotype. Nanopore sequencing showed a compound heterozygous state in FUT1, represented by the FUT1*01W.09 allele and a novel FUT1 allele carrying the c.[35C>T;133_136dupCGCC] variant. The FUT2 genotype was determined as FUT2*01/FUT2*01W.02.01.

conclusionThis study identifies a novel FUT1 allele characterized by the c.[35C>T;133_136dupCGCC] variant that impairs H antigen expression on red blood cells, thereby contributing to the understanding of FUT1 allele diversity.
