Comparison of hepatitis B surface antigen, anti-hepatitis B surface, and anti-hepatitis C virus prevalence in Syrian refugee pregnant women and Turkish pregnant women.
Article in Revista da Associacao Medica Brasileira (1992), 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers, 1 of them a synthesis that pooled 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.
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
objectiveIn this study, we aimed to determine and compare hepatitis B surface antigen level, anti-hepatitis B surface, and anti-hepatitis C virus positivity in Turkish pregnant women and Syrian refugee pregnant women residing in Turkey.
methodsThe study was conducted on Syrian refugee pregnant women aged 15-45 years and Turkish pregnant women who applied to state hospital's gynecology and obstetrics outpatient clinics between April 30, 2012, and April 30, 2022. In our study, 136,376 pregnant women (104,629 Turkish and 31,747 Syrian) tested for hepatitis B surface antigen, 72,035 pregnant women (53,070 Turkish and 18,965 Syrian) tested for anti-hepatitis B surface, and 120,611 pregnant women (92,514 Turkish and 28,097 Syrian) tested for anti-hepatitis C virus were included. The patients were divided into six groups for hepatitis B surface antigen, anti-hepatitis B surface, and anti-hepatitis C virus results based on their age: <20 years, 20-24 years, 25-29 years, 30-34 years, 35-39 years, and >40 years. For each age group, the results of Syrian refugee pregnant women and Turkish pregnant women were compared.
resultsHepatitis B surface antigen positivity and anti-hepatitis B surface positivity were significantly higher in Turkish pregnant women compared to Syrian refugee pregnant women. Anti-hepatitis C virus positivity was significantly higher in Syrian refugee pregnant women compared to Turkish pregnant women.
conclusionBased on the available data, we think that hepatitis B surface antigen, anti-hepatitis B surface, and anti-hepatitis C virus tests should be done routinely for pregnant women. Raising awareness among Syrian refugees about the hepatitis B virus vaccine as well as encouraging them to be vaccinated may reduce the negative impact of migration.
