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
The chromosome location, 11q21-23, is linked to loss of heterozygosity (LOH) in multiple tumors including those of breast, lung, and head and neck. To examine the process of LOH induction, the H292 cell line (human muco-epidermoid carcinoma) was irradiated or treated with anti-CD95 antibody, and individual clones isolated through two rounds of cloning. Regions of LOH were determined by screening a suite of eight polymorphic microsatellite markers covering 11p15-11q24 using fluorescent primers and genetic analyzer peak discrimination. LOH induction was observed extending through 11q21.1-11q23.3 in 6/49 of clones surviving 4 Gy and 8/50 after 8 Gy. Analysis of selected clones by Affymetrix 6.0 single nucleotide polymorphism (SNP) arrays confirmed the initial assessment indicating a consistent 27.3-27.7 Mbp deletion in multiple clones. The telomeric border of LOH mapped to a 1 Mbp region of elevated recombination. Whole genome analysis of SNP data indicated that site-restricted LOH also occurred across multiple additional genomic locations. These data indicate that 11q21.1-11q23.3, and potentially other regions of this cell line are sites of intrinsic cell-specific instability leading to LOH after irradiation. Such deletions may subsequently be propagated by genetic selection and clonal expansion.
