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

Hepatitis B virus (HBV) vaccine is composed of the purified hepatitis B surface antigen (HBsAg) that is produced by recombinant DNA technology. The neutralizing antibodies induced by vaccination target mainly the "a" determinant, aa124-147, of the outer viral envelope (HBsAg). In the present work, we demonstrate a case study for vaccinated patient that is infected with a vaccine escape HBV strain (Eg200). Characterization of the isolate Eg200 showed that it belongs to the genotype D and an uncommon sub-genotype in Egypt; D9. The DNA sequence encoding HBsAg was sequenced. Mutational analysis of the HBsAg showed a double mutation in the "a" determinant of this HBV isolate; T125M and P127T. However, such substitutions were found to be conserved to the detected serotype, ayw3, of Eg200 isolate. This case report indicates that continuous characterization of breakthrough vaccine escape strains of HBV is essential to develop the immunization strategies against HBV infection.
