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

BACKGROUND/

aimThe natural course of hepatitis B virus (HBV) infection is likely related to host immune factors. Interleukin-18 (IL-18) plays a significant role in immune defense. This study was undertaken to determine the association between the presence of hepatocellular carcinoma (HCC) and single-nucleotide polymorphisms (SNPs) in the IL-18 gene in HBV-infected patients.

methodsBetween March 2002 and December 2004, 730 Korean subjects were enrolled in two different groups: (1) chronic carrier without HCC (n=637) and (2) HCC (n=93). We analyzed SNPs at four polymorphic sites in the IL-18 gene at positions -667G>T, -148G>C, +8925C>G, and +13925A>C in the study subjects. To evaluate the functional significance of SNPs in the IL-18 gene promoter region, we performed a reporter gene assay in HepG2 and Hep3B cells transfected with different alleles.

resultsThe IL-18 -148C allele, +8925G allele, +13925C allele, and haplotype 3 (TCGC) were associated with the presence of HCC in codominant and dominant models. Furthermore, functional analyses using the reporter gene assay revealed that the -148C allele conferred significantly lower promoter activity.

conclusionsThis study indicates that the -148C, +8925G, and +13925C alleles of the IL-18 gene are associated with the presence of HCC and the 148G>C SNP is functionally important in determining disease outcome.
