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

Tumor necrosis factor (TNF) and lymphotoxin alpha (LTA) influence a variety of cellular responses and play a complex role in the immune response. Several single nucleotide polymorphisms (SNPs) have been reported in these major histocompatibility complex (MHC)-linked loci; however, a comprehensive examination of polymorphisms in the promoter regions of TNF and LTA has not been carried out and was undertaken here. Seven novel SNPs in LTA were identified by sequence analysis of 69 samples. Eight novel TNF alleles and 16 novel LTA alleles were designated. The TNF alleles clustered into two closely related groups, while the LTA alleles clustered into three distinct groups using phylogenetic and percentage difference analyses. A total of 52 unique TNF-LTA-HLA haplotypes are reported. There appear to be some associations between TNF/LTA alleles and HLA haplotypes, but not with specific HLA alleles. The majority of the SNPs appear to be randomly associated within and between the two loci except for the LTA SNPs at -293, +81 and +369. These observations may provide an explanation for the oftentimes contradictory results of studies associating individual cytokine gene SNPs with expression level phenotypes, HLA and disease.
