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: Aplastic anemia (AA) is a rare but serious blood disorder defined by autoimmune-driven destruction of bone marrow stem and progenitor cells. HLA polymorphisms are AA risk factors, with population-specific associations influencing disease susceptibility, treatment response, and transplant outcomes. While the genetic pathways driving AA development remain incompletely elucidated, a link between HLA variants and AA predisposition has been documented across diverse ethnic groups, though not in Central Asian communities, particularly in Kazakhstan. Objective: We investigated the relationship between HLA Class I and Class II alleles and the risk of AA in the Kazakhstani population using high-resolution NGS genotyping. Methods: The study included 91 patients with AA and 250 unrelated controls selected from the national registry of hematopoietic stem cell donors. HLA class I (A/C/B) and class II (DRB1/DQA1/DQB1/DPB1) high-resolution genotyping was conducted using NGS. Statistical significance was assessed with chi-square tests. Results: Class II alleles showed stronger associations with AA than Class I alleles. Novel HLA associations with strong effect sizes (ORs >69) were identified, including the first-ever reported associations between Conclusions: Class II alleles, including those within
