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) replication requires the viral polymerase to reverse transcribe the 3.5-kb pregenomic viral RNA within the nucleocapsid. It has been proposed that a sequence element designated phi (phi), which is located 32 nucleotides upstream of the 3' DR1 pregenomic RNA sequence and is complementary to epsilon, is required for efficient minus-strand synthesis because it may mediate the translocation of the viral polymerase plus the three nucleotide primer from epsilon to DR1. A mutation in phi has been identified which can be compensated for with a complementary mutation in epsilon. This observation supports the suggestion that epsilon and phi base pair during the process of polymerase translocation from epsilon to DR1. However, additional mutations in phi were not complemented by the corresponding mutations in epsilon indicating that the functional recognition of epsilon and epsilon/phi stem-loop structures by polymerase probably requires both sequence- and structure-specific information.
