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

A simple technique for the identification of common genotypes of the hepatitis B virus (HBV) remains to be identified. The present study was conducted to establish such a methodology. Four plasmids of genotypes A‑D and 123 clinical serum specimens of HBV‑infected patients were genotyped. HBV genotypes would be detected successfully when the HBV genotype reached a viral load of 1 x 103 copies/ml or the BC genotype mixed samples reached a 5% level. The lower limit of detection of HBV DNA in serum specimens was determined to be 2.14x102 IU/ml. The assay sensitivity and specificity were 100% and the consistency was demonstrated to reach as high as 90.24 and 100% compared with that of the DNA sequencing and cloning. The frequencies of the genotypes B, C, BC, BD and BCD were found to be 65.0, 23.6, 7.3, 3.3 and 0.8%, respectively. The accuracy of detection of the mixed infections was also higher using the rapid and simple SNaPshot method compared with that achieved with the DNA sequencing methods. The results of the present study indicated that the SNaPshot technique accurately distinguishes the HBV genotypes A‑D and is able to be readily applied as a monitoring tool in HBV prognosis and treatment.
