Review in The Indian journal of medical research, 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 22 papers, 2 of them syntheses that pooled it.

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

Chronic hepatitis B virus (HBV) infection affects millions of people worldwide and about a half million people die every year. India represents the second largest pool of chronic HBV infection worldwide with an estimated 40 million infected people. The prevalence of chronic HBV infection in pregnant women is shown to be 0.82 per cent with the risk of mother-to-child vertical transmission. Hepatitis B e antigen (HBeAg) positivity indicates replicative form of HBV which may play a role in immunotolerance in utero by crossing the placenta. In case of HBeAg positivity and high viral load of mother, HBV immunoglobulin is preferably given along with HBV vaccination. Antiviral therapy is recommended for use in the third trimester of pregnancy to reduce the perinatal transmission of HBV, however, use of antiviral therapy should be individualized during pregnancy. Chronic HBV infection in neonates is linked with strong presence of Tregs (T regulatory cells) and defective CD8 T cells pool to produce interferon (IFN)-γ. T cell receptor (TCRζ) chain defects were also associated with decreased CD8 T cell dysfunction. Decreased TCRζ expression could be due to persistent intrauterine exposure of the viral antigens early in embryonic development leading to immune tolerance to HBV antigens in the newborns positive for hepatitis B surface antigen (HBsAg+ve). Therefore, due to HBV infection, T cell tolerance to HBV-antigen may probably leave the newborn as a chronic carrier. However, HBV vaccination may have benefits in restoring acquired immunity and better production of HBV specific antibodies.
