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
introductionThe Prevention of Mother-To-Child Transmission (PMTCT) of Hepatitis B Virus (HBV) infection is a crucial strategy for achieving global HBV elimination by 2030. As HBV testing forms the foundation of effective PMTCT programs, empowering women of reproductive age to accept HBV testing and screening services is essential. This study applied the Theory of Planned Behaviour to investigate the impact of psychosocial factors, including attitude, subjective norm, perceived behavioural control, and risk perception, on HBV testing intentions among women of reproductive age.
methodsA hospital-based cross-sectional study was conducted among 400 non-pregnant women aged 18-49 years attending child welfare and family planning clinics in rural northern Ghana. Participants were selected using simple random sampling and completed a structured, pretested questionnaire based on constructs from the Theory of Planned Behaviour. Composite sum scores were computed for each construct, and internal consistency was assessed using Cronbach's alpha. Spearman's correlation and hierarchical multiple regression analyses were performed using SPSS version 26, with statistical significance set at p < .05.
resultsThe mean age of participants was 27.12 years (SD = 5.8). In the main-effects regression model, attitude (β = 0.650, p < .001), perceived behavioural control (β = 0.275, p < .001), and risk perception (β = 0.061, p = .022) were significant predictors of HBV testing intention, while subjective norms were not statistically significant. The model explained 75.3% of the variance in testing intention (R² = 0.753). When the interaction between attitude and subjective norms was added, the interaction term was statistically significant (β = -0.108, p < .001), accounting for an additional 1.1% of variance (ΔR² = 0.011).
conclusionAttitude and perceived behavioural control were the primary predictors of HBV testing intention among women of reproductive age in rural northern Ghana. Risk perception showed a smaller association with intention, while subjective norms did not independently predict intention but moderated the relationship between attitude and intention. Interventions aimed at increasing HBV testing intention should prioritise strengthening positive attitudes and enhancing women's perceived ability to access testing services. CLINICAL
trial registrationThe study is a cross-sectional study and hence did not involve any experimentation or trial; clinical trial registration was not applicable in this case.
