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

Objectives: We here report the distribution of the human leukocyte antigen (HLA)-A, -B, -C, -DRB1, and -DQB1 alleles among 149 units of Vietnamese umbilical cord blood samples and deduced their most probable HLA haplotypes for HLA-A/B loci, HLA-B/C loci, HLA-DRB1/DQB1 loci, HLA-A/C/B loci, HLA-A/C/B/DRB1 loci, and HLA-A/C/B/DRB1/DQB1 loci. Our objective is to reveal the unprecedented information on the distribution of HLA alleles in the Vietnamese cord blood and to find out the most probable HLA haplotypes associated with the various HLA alleles detected in the cohort of 149 cord blood specimens. Materials and Methods: The material for this study was umbilical cord blood samples, preserved in acid citrate dextrose anticoagulants. The blood donors were umbilical cord blood donors whose parents voluntarily donated their newborn baby's cord blood to the Blood Transfusion and Hematology Hospital, Ho Chi Minh City, Vietnam. DNA sequence-based typing of the Sanger's sequencing method was performed for the HLA allelic typing. Target exon sequence amplifications were achieved by polymerase chain reaction (PCR), and the resulting amplicons were sequenced by BigDye Terminator Cycle Sequencing Ready Reaction Kit, according to the manufacturer's protocols. Results: In the total number of 149 randomized cord blood samples studied, we detected distinctive 22 HLA-A alleles, 23 HLA-C alleles, 44 HLA-B alleles, 27 HLA-DRB1 alleles, and 15 HLA-DQB1 alleles. In addition, we determined the most probable HLA haplotypes for the alleles detected. Conclusion: Our findings in this study are useful in research for the comprehensive understanding of the distribution of HLA alleles and their associated HLA haplotypes in Vietnamese cord blood. Further, the cord blood with HLA typing determined is now ready for matching search purpose for patients who are looking for suitable hematopoietic stem cell donations for transplantation therapeutic applications.
