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.

Abstract

objectiveUsing acute appendicitis as a model, we tested the hypothesis that polymorphisms in genes involved in host defense can be associated with the severity of local infection-inflammation in humans. SUMMARY BACKGROUND DATA: Innate immunity is the body's front-line system for antimicrobial host defense. Local inflammation is a major innate immune mechanism for containing and destroying microbes, but it may also contribute to tissue injury.

methodsWe studied 134 patients with acute appendicitis treated at an urban hospital. We looked for associations between the severity of appendicitis (uncomplicated vs. perforated or gangrenous), plasma and peritoneal cytokine concentrations, and single nucleotide polymorphisms in genes involved in recognizing bacterial molecules [CD14 (-159 C-->T); TLR4 (896 A-->G)] and in mounting an inflammatory response [IL-6 (-174 G-->C), TNF-alpha (-308 G-->A), IL-1beta (-31 C -->T)].

resultsNinety-one patients (68%) had uncomplicated appendicitis and 43 (32%) had complicated disease. The SNPs in the CD14, TLR4, IL-1beta, and TNF-alpha genes were not associated with the severity of appendicitis. A strong association was found between C-allele carriage at -174 in the IL-6 gene and decreased risk of complicated disease (adjusted odds ratio = 0.24, 95% CI = 0.07-0.76). Lower plasma and peritoneal fluid IL-6 concentrations in the IL-6 -174 C-carriers than in the GG homozygotes suggest that this polymorphism contributes to decreased IL-6 production in vivo.

conclusionsPolymorphism in the IL-6 gene was associated with the severity of appendicitis, even after adjustment for duration of symptoms. The risk for developing appendiceal perforation or gangrene may be determined, in part, by variation in the IL-6 gene.
