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
Rapid industrialization, rise in population, and urbanization have led to severe environmental degradation and health concerns for inhabitants due to regular household waste (RHW). Implementing sustainable waste management practices, such as regular household waste recycling, is an imminent need in Saudi Arabia and other nations. Yet, the analysis of the awareness regarding RHW recycling and its influencing elements in the Kingdom of Saudi Arabia (KSA) has rarely been conducted. Efficient management of home waste is currently a major concern, particularly in economically developing countries, as inappropriate disposal of waste results in financial losses and detrimental effects on the environment and public health. The objective of this study is to assess the level of awareness among Saudi households on RHW, the environmental issues associated with improper waste disposal, and their readiness to participate in the recycling of RHW. Therefore, we conducted a two-stage analytic investigation that included a total of 909 households from different areas of Saudi Arabia. In addition to the analysis of questionnaire responses, partial dependency (PDP) analysis was also conducted using two supervised machine learning algorithms, Multi-Layer Perceptron (MLP) and Decision Tree (DT), to evaluate how sociodemographic factors influence waste recycling awareness. Based on the study results, most respondents are knowledgeable and worried about the adverse environmental effects of solid waste. Most respondents are motivated to support a large-scale recycling program, provided enough facilities are available. Also, the PDP analysis revealed that sociodemographic factors such as age, gender, salary, and marital status also significantly impact the awareness of waste recycling. Finally, considering the rising amount of waste produced by the Saudi population, the authorities must implement a recycling program to address this harmful waste and promote the development of a sustainable world.
