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

IL-18, initially defined as a potent inducer of IFN- gamma production, is a systemic, multifunctional cytokine with both pro-cancerous and anti-cancer activities. The contribution of the IL-18 promoter polymorphisms at positions -607 (C/A) and -137 (G/C) to cancer development has been reported. We sought to examine IL-18 serum level and its polymorphisms in Iranian women with ovarian cancer. Single nucleotide polymorphisms (SNPs) at positions -607 (C/A) and -137 (G/C) were analyzed by allele-specific polymerase chain reaction in 85 women with ovarian cancer and 158 healthy controls. IL-18 serum level was determined using ELISA method. No significant association was found between the allele, genotype, and haplotype distributions of the SNPs and ovarian cancer. Mean IL-18 serum level was significantly higher in patients than in controls (P = 0.008). Comparing IL-18 serum levels with genotypes at positions -607 and -137 revealed no significant difference. No association was also found between IL-18 levels and the disease stage. In conclusion, our results indicate that IL-18 promoter polymorphisms at positions -607 (C/A) and -137 (G/C) appear not to confer susceptibility to ovarian cancer in Iranian population; however, IL-18 serum level increases in ovarian cancer patients.
