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
Breast cancer is a leading cause of cancer-related deaths worldwide, with most cases in Bangladesh diagnosed at advanced stages due to limited awareness and late detection. While breast self-examination (BSE) is a simple, cost-free method for early detection, its practice among adolescents remains poorly understood. This study aims to explore breast cancer knowledge, BSE practices, and barriers among adolescent girls in a semi-urban area, addressing a critical gap in early prevention efforts. A cross-sectional study was carried out with 384 adolescent girls from four renowned schools in a semi-urban area of Dhaka, Bangladesh. Participants were sampled at school from January to April 2025. Proportionate stratified random sampling was conducted to determine the study sample from each school. A validated semi-structured self-reported questionnaire was employed to collect data from participants during the survey period. Among the participants, only 45.3% had heard of BSE and just 4.6% reported ever practicing it. Overall, breast cancer knowledge was low, with a mean score of 9.49 out of 31 (30.6%). Regression analyses indicated that higher breast cancer knowledge scores were significantly associated with having a science academic background (β = 1.82, p < 0.01), higher family income (β = 1.14, p < 0.05), and prior BSE practice (β = 2.36, p < 0.001). A strong positive correlation was observed between overall knowledge and BSE practice (r = 0.54, p = 0.001). Students from the science section were significantly more likely to practice BSE than those from the humanities section (OR = 9.47, 95% CI: 1.21-73.89, p = 0.032). Participants who received BSE information from health workers were approximately nine times more likely to practice BSE than those who did not (OR = 9.62, 95% CI: 2.30-40.20, p = 0.002). The study demonstrates critically low levels of breast cancer knowledge and BSE practice among adolescent girls, with knowledge strongly influencing practice. These findings underscore the need for culturally appropriate, school-based educational interventions to improve awareness, promote early detection behaviors, and potentially reduce future breast cancer morbidity and mortality in Bangladesh.
