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
backgroundHemodialysis patients are at increased risk of acquiring blood-borne infections such as human immunodeficiency virus (HIV), hepatitis B virus (HBV) and hepatitis C virus (HCV) infections because of their susceptibility to invasive procedures and their immunosuppressive state. This study aimed to determine the prevalence of HIV, HBV, and HCV among hemodialysis patients at the Buea Regional Hospital (BRH) and identify potential risk factors for transmission.
methodsA facility-based cross-sectional study was conducted between April and June 2024 among patients receiving maintenance hemodialysis at the BRH, Cameroon. A minimum sample size of 88 participants was calculated; 100 eligible patients were enrolled. Data were collected using a structured questionnaire to assess sociodemographic characteristics, risk factors, and knowledge of HIV, HBV, and HCV. Serological testing for HIV, HBV, and HCV was performed using rapid diagnostic test kits according to manufacturers’ instructions. Infection prevention practices were assessed through direct observation of hemodialysis sessions. Data were analyzed using SPSS Statistics version 22.0, with associations assessed at p < 0.05.
resultsThe prevalence rates of HIV, HBV, and HCV were 17.0%, 9.0%, and 3.0%, respectively. HIV positivity was significantly associated with lower education and a history of sexually transmitted infections. Most participants demonstrated moderate to good knowledge of these infections; however, only 38% recognized HBV as vaccine-preventable, and just 5% reported receiving the vaccine. Observations revealed gaps in infection control, including inadequate hand hygiene and absence of dedicated areas for patients with known infections.
conclusionHemodialysis patients at BRH carry a high burden of blood-borne infections. Strengthened vaccination programs, improved infection control, and larger multi-center studies are needed to reduce transmission risks among patients with chronic kidney disease in Cameroon.
