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
Background: Health literacy is essential for informed decision-making and cancer prevention. In Malaysia, limited health literacy contributes to delayed breast cancer diagnoses and poorer outcomes among disadvantaged populations. However, there is no validated instrument for assessing breast cancer screening health literacy. Accordingly, this study aimed to develop and validate such a questionnaire for Malaysian adults. Methods: A three-phase, multi-method design was employed. Phase One involved item generation through a systematic review, online surveys, expert validation and translation. Phase Two included cognitive debriefing and an analysis of test-retest reliability. Phase Three consisted of a cross-sectional survey of 779 adults (mean age 36.6 years; 66% female) attending clinics in Selangor and Johor. The scale was evaluated psychometrically with exploratory factor analysis, internal consistency and confirmatory factor analysis using covariance-based structural equation modelling. Results: The initial 66-item tool was refined to a questionnaire with 41 items in seven domains showing strong reliability (Cronbach's Conclusion: The validated 41-item Breast Cancer Screening Health Literacy Questionnaire is a reliable and culturally appropriate tool in Bahasa Malaysia that can be employed in clinical and community settings to identify literacy gaps, develop tailored health promotion strategies and strengthen early detection initiatives.
