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

objectivesThe population in Iran is a genetic admixture of the ancestral Aryan and other populations neighboring Iran. Different ethnic groups in Iran show wide regional distributions for many human leukocyte antigen (HLA) alleles. Therefore, it is necessary and sensible to study the differences in HLA allele distribution in different area. We studied the HLA class I and II allele frequencies in a large unrelated healthy Iranian population from Mashhad in the Northeast region. MATERIALS AND

methodsFive hundred unrelated healthy adult individuals borne and living in Mashhad, Northeast of Iran, were genotyped for HLA-A, B and HLA-DRB1 alleles using PCR with low resolution sequence specific primers (SSP-PCR) technique.

resultsA total of 14 HLA-A, 24 HLA-B and 10 HLA-DRB1 alleles were spread throughout the studied population with distinct allele frequencies. At the HLA-A locus, HLA-A*02 was found to be the most frequent allele, with a frequency of 20.9%. The most common HLA-B alleles was B*35 (16.4%). The two most common observed alleles in HLA class II alleles were DRB1*15 (20.0%) followed by DRB1*13 (16.2%).

conclusionThis study is the first on the HLA class I and II allele frequencies in Northeastern Iranian population living in Mashhad. Distribution of HLA-A and B loci showed some similarities with those of other Iranians. Some difference in HLA-DRB1 polymorphisms however was observed. Considering the highly mixed population of Mashhad, the finding was not unexpected.
