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) e antigen (HBeAg) was discovered in the sera of HBV patients nearly 50 years ago. It is not essential for HBV to infect or replicate in hepatocytes. Earlier clinical studies suggested that this antigen might play an important role for HBV to establish persistence in babies after its mother-to-child transmission. Subsequent clinical studies also suggested that HBeAg might have immunomodulatory activities. In recent years, a large body of information on how HBeAg might modulate host immunity was published. In this review, we summarize recent research progresses on the immunomodulatory activities of HBeAg and discuss how these activities of HBeAg may promote HBV persistence.
