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

BACKGROUND &

aimsNamibia has been suffering from an outbreak of hepatitis E genotype 2 since 2017. As nearly half of hepatitis E-related deaths were among pregnant and postpartum women, we analysed maternal and fetal outcomes of pregnancies complicated by acute hepatitis E and assessed whether HIV-status impacted on outcome.

methodsA retrospective cross-sectional study was performed at Windhoek Hospital Complex. Pregnant and postpartum women, admitted between 13 October 2017 and 31 May 2019 with reactive IgM for Hepatitis E, were included. Outcomes were acute liver failure (ALF), maternal death, miscarriage, intra-uterine fetal death and neonatal death. Odds ratios (OR) and 95% confidence interval (CI) were calculated.

resultsSeventy women were included. ALF occurred in 28 (40.0%) of whom 13 died amounting to a case fatality rate of 18.6%. Sixteen women (22.9%) were HIV infected, compared to 16.8% among the general pregnant population (OR 1.47, 95% CI 0.84-2.57, P = .17). ALF occurred in 4/5 (80%) HIV infected women not adherent to antiretroviral therapy compared to 1/8 (12.5%) women adherent to antiretroviral therapy (OR 28.0, 95% CI 1.4-580.6). There were 10 miscarriages (14.3%), five intra-uterine fetal deaths (7.1%) and four neonatal deaths (5.7%).

conclusionsOne in five pregnant women with Hepatitis E genotype 2 died, which is comparable to genotype 1 outbreaks. Despite small numbers, HIV infected women receiving antiretroviral therapy appear to be less likely to develop ALF in contrast with HIV infected women not on treatment. As there is currently no curative treatment, this phenomenon needs to be assessed in larger cohorts.
