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

Naturally occurring mutations in surface proteins of Hepatitis B virus (HBV) usually result in altered hepatitis B surface antigen (HBsAg) secretion efficiency. In the present study, we reported two conserved residues, M75 and M103 with respect to HBsAg, mutations of which not only attenuated HBsAg secretion (M75 only), but also suppressed HBV genome replication without compromising the overlapping p-gene product. We also found M75 and M103 can initiate truncated surface protein (TSPs) synthesis upon over-expression of full-length surface proteins, which may possibly contribute to HBV genome replication. However, attempts to rescue replication-defective HBV mutant by co-expression of TSPs initiated from M75 or M103 were unsuccessful, which indicated surface proteins rather than the putative TSPs were involved in regulation of HBV genome replication.
