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
backgroundThe prevention of mother-to-child transmission of hepatitis B virus (HBV) is essential to achieve the World Health Organization's goal of eliminating HBV as a public health threat by 2030. This study examines the management of HBV in pregnant women and newborns at a large tertiary health service in Victoria, Australia.
aimsTo evaluate the timely administration of hepatitis B immune globulin (HBIG) and the birth dose vaccine to infants born to mothers with chronic hepatitis B (CHB) and to assess maternal referral to specialist care, viral load (VL) testing and antiviral therapy.
methodsThis retrospective study reviewed medical records of women with CHB who delivered at Monash Health from 2014 to 2022. Data were extracted on maternal referral to specialist care, VL testing, antiviral use and administration timing of HBIG (within 12 h) and hepatitis B vaccine (within 24 h) to newborns.
resultsOf the 895 infants, 99.7% received both HBIG and the birth dose vaccine; 97.4% received the vaccine within 12 h, and 88.3% received HBIG within the recommended 12-h window. Maternal referral rates to specialist care were 83.1%, with 91.06% undergoing VL testing during pregnancy. Antiviral therapy was administered to 16% of women.
conclusionsHigh uptake of HBV immunoprophylaxis was observed, with most infants receiving timely vaccination and HBIG. However, variability exists in maternal referral and antiviral treatment. Continued efforts are needed to improve comprehensive care and reduce transmission risk across diverse settings.
