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 and Aims: Biodegradable packaging has gained increasing attention globally as an eco-friendly alternative to conventional plastics with the aim of reducing environmental pollution and promoting sustainability. This study aimed to examine university students' knowledge, attitudes, and practices (KAP) along with the barriers and environmental concerns regarding biodegradable packaging in southern Bangladesh. Methods: A cross-sectional survey was conducted between June and July 2025, involving 387 students through convenience sampling and self-reported interviews. Results: The findings showed moderate KAP toward biodegradable packaging (54.7%, 58.9%, and 57%, respectively). Knowledge was significantly higher among participants aged 21-23 and ≥ 24 years, hostel residents, and those whose mothers had completed higher secondary education. Attitudes were higher among females, students aged 21-23, and students in advanced study years. Practices were significantly higher among females, and students in the later stages of their studies. By contrast, students from rural areas demonstrated significantly lower attitudes and practices. Additionally, the lack of exposure to biodegradable packaging in university courses, absence of formal training on environmental conservation, non-participation in environmental volunteer work, and not following eco-friendly social media pages exhibited lower levels of KAP. Difficulties in finding biodegradable packages in the local market were the most commonly described barriers (14.1%) among the participants. Pollution of rivers, oceans, and natural areas by plastic packaging (11.9%) was reported as the most frightening environmental danger identified by the participants. Conclusion: The results highlight that focused education, training, and increased accessibility of biodegradable packaging are essential to enhance students' KAP and overcome barriers to sustainable adoption, particularly among specific demographic groups and in rural areas of Bangladesh.
