Synthesis in Digestive diseases and sciences, 2014. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT02995005 (Prevention of Mother-to-child Transmission of Hepatitis B Virus), which is not on this map. Cited by 15 papers, 4 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.

Abstract

backgroundMother-to-child transmission (MTCT) is the main mode of spread of hepatitis B virus (HBV) in China. We performed a meta-analysis to compare the effects of three measures for prevention of MTCT.

methodsA meta-analysis was performed on randomized controlled trials and non-randomized studies comparing the index of MTCT among five groups of pregnant women: hepatitis B immunoglobulin (HBIG) administration, antiviral treatment, placebo, elective caesarean section, and vaginal delivery.

resultsCompared with the control group, the incidence of HBV intrauterine infection (RR = 0.42, 95 % CI 0.27-0.64, P < 0.0001) and the number of chronic hepatitis B (CHB) infants (RR = 0.44, 95 % CI 0.32-0.61, P < 0.00001) were lower in the HBIG administration group. In the antiviral treatment group, serum HBV DNA levels were lower (MD = -4.01, 95 % CI -5.07 to -2.94, P < 0.00001) at the time of delivery, and normalization of ALT levels was better (RR = 1.11, 95 % CI 1.06-1.17, P < 0.0001). Infant serum HBsAg positivity (RR = 0.45, 95 % CI 0.22-0.91, P = 0.03) and incidence of infant HBV transmission RR = 0.06, 95 % CI 0.01-0.24, P < 0.0001) were reduced in antiviral the treatment group. Infant serum anti-HBs positivity at birth (RR = 1.24, 95 % CI 0.89-1.74, P = 0.2) or at 6-7 months (RR = 0.98, 95 % CI 0.86-1.11, P = 0.73) was not significantly different between the caesarean section and vaginal delivery groups. The incidence of infant CHB infection may have been higher in the vaginal delivery group (RR = 2.20, 95 % CI 1.02-4.74, P = 0.04).

conclusionsAdministration of HBIG or antiviral therapy to HBV carrier mothers during pregnancy is effective in reducing MTCT.
