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
introductionPlastic pollution, particularly from single-use plastics (SUPs), is an increasing environmental problem, especially for coastal communities dependent on marine ecosystems for their livelihood, food, and recreation. The Korle-Gonno community in Ghana epitomizes this: inadequate waste management systems and heavy reliance on SUPs. This study aimed to explore the drivers of consumer attitudes toward SUPs to inform effective interventions.
methodsA descriptive cross-sectional study was conducted among 198 residents of Korle-Gonno. The study used a multi-stage sampling method to select participants, targeting adults who had lived in the community for at least five years. Data was collected using a structured questionnaire that assessed socio-demographics, knowledge, concerns, attitudes, and practices regarding SUPs. Scores were categorized into low, moderate, and high levels, and data were analyzed using STATA 17.0. Descriptive and inferential statistics were analyzed, including chi-square tests and logistic regression.
resultsThe study showed that 51% of the respondents have low knowledge of SUPs and although they considered SUPs as one of the major contributors to pollution, only 10.1% reported recycling plastics, while most relied on improper methods of plastic disposal. Important predictors of positive attitude towards the reduction of SUPs were: high levels of concern (aOR=2.37, 95% CI = 1.09-5.15) and good perception of environmental impact (aOR=4.59, 95% CI = 2.15-10.83). Those who had lived in the community for more than 20 years were likely to have positive attitudes (aOR=2.45, 95% CI = 1.04-5.77).
conclusionSUP pollution in Korle-Gonno is fueled by a lack of knowledge, inappropriate practices, and inadequate infrastructure. While these are major challenges, the community strongly supports regulation and corporate responsibility. Public education, improvement of the recycling system, and promotion of biodegradable alternatives are critical intervention strategies to solve this problem sustainably.
