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
Aims: This study aimed to determine the seroprevalence of hepatitis B virus (HBV) among newly diagnosed cancer patients in Khartoum State, Sudan, prior to chemotherapy initiation and to identify associated risk factors. Methods and Results: A cross-sectional study was conducted from October 2022 to April 2023 at various oncology centers in Khartoum State. A total of 300 newly diagnosed cancer patients, aged 18 years and older, were included. Blood samples were screened for Hepatitis B surface antigen (HBsAg) using a rapid immunochromatographic test (ICT) and confirmed by enzyme-linked immunosorbent assay (ELISA). The study found that 31 patients (10.3%) were HBsAg positive. A significant association was observed between HBV positivity and patients' history of blood transfusions (41.9% of positive cases), as well as geographic origin, with higher rates among those from Western Sudan (44.7%) and Central Sudan (40.6%). Patients diagnosed with hematological malignancies exhibited the highest HBV prevalence. Statistical analysis revealed significant correlations between HBV positivity and factors such as age, gender, residence, and transfusion history, indicating these as key risk factors. Conclusion: The study reveals a notable HBV seroprevalence among cancer patients in Khartoum, particularly linked to blood transfusion history and specific regions. These findings emphasize the need for routine HBV screening in oncology patients before chemotherapy to prevent reactivation and improve clinical outcomes.
