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

Patients with hepatitis B virus (HBV) infection may develop severe chronic liver disease. Carriers of HBV have an increased risk of developing cirrhosis, hepatic decompensation, and hepatocellular carcinoma. Worldwide an estimated 350 million people are infected with HBV, and 15-40% will develop serious sequelae in their lifetime. In our study we investigated the association of single nucleotide polymorphisms (SNPs) in the first exon and promoter region of the mannose-binding lectin gene 2 (MBL2) situated on chromosome 10, with susceptibility to HBV infection. One-hundred and two patients infected with HBV were included in this study, and 232 uninfected individuals were used as healthy controls. Genotyping of the first exon (alleles A/O) was performed using a melting temperature assay. Genotyping of the promoter region (-550 H/L; -221 Y/X) was performed using the Taqman PCR technique. In the HBV-infected group we found a significantly increased frequency of haplotypes associated with low serum MBL. Our findings may indicate that MBL has a protective role against HBV infection in the studied population.
