Loss of heterozygosity at the human leukocyte antigen locus in thymic epithelial tumors.
Article in Thoracic cancer, 2015. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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.
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
backgroundTo study the relationship between loss of heterozygosity (LOH) at the human leukocyte antigen (HLA) locus and the pathogenicity and clinicopathological features of thymic epithelial tumors (TET).
methodsTumor and adjacent normal tissues were isolated from 36 TET patients. Five microsatellite loci (D6S1666, D6S265, D6S273, DS6276, and D6S291) within the HLA locus were amplified by polymerase chain reaction. DNA sequencing was used to measure the frequency of microsatellite LOH.
resultsLOH was identified in at least one locus in 83.6% of TET patients. LOH frequency at D6S1666, D6S265, D6S273, D6S276, and D6S291 was 44.4%, 16.7%, 30.5%, 38.9%, and 36.1% respectively. There was no significant association between LOH frequency in TET with tumor severity, or in the presence or absence of myasthenia gravis.
conclusionsD6S1666, D6S265, D6S273, DS6S276, and D6S29 are sensitive loci for studying microsatellite LOH in TET. LOH within the HLA complex is implicated in the occurrence and development of TET, with the HLA-DQA1 gene likely involved. However, an understanding of the relationship between LOH and the clinicopathological features of TET requires a larger sample size than that of the present study.
