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
We have used a novel approach to investigate the histone H4 acetylation status at X-inactivated genes compared with their active counterparts. Immunoprecipitation with a sheep antibody that preferentially binds multiply-acetylated H4 isoforms was used to select hyperacetylated chromatin from a human female lymphoblastoid cell line exhibiting non-random X-inactivation as a result of an X/autosome translocation. The distribution of active and inactive gene sequences between the immunoprecipitated and bulk chromatin was compared at four X-linked loci containing intragenic polymorphic microsatellite repeats to allow identification of individual alleles by polymerase chain reaction. We find that DNA sequences corresponding to transcriptionally silent alleles are consistently under-represented in the hyperacetylated fraction. As the microsatellite repeat sequences used to identify alleles range in distance from 6.5 kb to 25 kb downstream of promoters, we conclude that differential H4 acetylation of active and silent chromatin is not confined to regions involved in the initiation of transcription, contrary to previous reports.
