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
Eight years after WHO adopted a resolution to eliminate hepatitis B by the year 2030, the disease remains a global public health concern, with vertical transmission of HBV being a major obstacle to this goal. Our study aimed to determine the HBV infection status of pregnant women in South Africa at a national level to evaluate the risk of vertical transmission and provide evidence for public health decision-making. We conducted HBsAg testing on 1,942 HIV-uninfected and 2,312 HIV-infected pregnant women from South Africa's public health sector in 2017, followed by HBeAg testing on HBsAg-positive samples. Our data were stratified by five-year age groups and province. The overall HBV prevalence was 11.24% (478/4,254), significantly higher among HIV-infected women (15.83%) compared to HIV-uninfected women (5.77%, p = 0.007). HBV prevalence was highest among women 40-44 years (14.00%) and in Limpopo Province (19.35%). Coinfection rates of HIV-HBV ranged from 14.00% to 17.00% among women 15-44 years, and provincially, rates were highest in Limpopo, North West, and Western Cape Provinces (>20%). HBeAg prevalence among HBsAg positive women was 9.48%, with higher rates among HIV infected women (11.29%) compared to HIV-uninfected women (7.34%, p = 0.7931). HBeAg prevalence was highest among women 15-19 (10.81%), 20-24 (11.88%) and 40-44 years (25.00%), and provincially, highest in North West (26.67%). Our findings highlight the significant prevalence of HBV infection among pregnant women in 2017, emphasising concerns about vertical transmission, particularly given the high prevalence of HBeAg among HBsAg-positive women. We advocate for the prompt implementation of a universal birth dose of the HBV vaccine in South Africa to augment existing vaccination schedules and mitigate the risk of vertical transmission, thereby advancing progress towards WHO elimination targets.
