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
introductionThe improper disposal of unused and expired medications poses significant environmental hazards and increases the risk of human harm. Even in countries with established policies for safe disposal, improper practices persist. In Nigeria, where there is a lack of stringent policies on medication disposal, this issue may be more pronounced. This study aims to assess the patterns of disposal of unused and expired medications among outpatients in selected hospitals in Ibadan.
methodsA cross-sectional, questionnaire-based study was conducted between December 2023 and February 2024. The survey was administered by interviewers to consenting outpatients at three healthcare facilities in Ibadan. Statistical analysis was performed using SPSS version 26, with a p-value of < 0.05 considered statistically significant.
resultsA total of 864 outpatients participated in the study, with a mean age of 45.1 ± 14.92 years. More than two-fifths of participants had secondary education, while nearly one-third had tertiary education. About two-thirds (66.3%) of the respondents reported obtaining their medications through self-medication. Approximately 39.1% of participants always checked the expiration dates before purchasing medications, while 24.7% did so before reusing them. Majority (70.8%) reported having unused medications at home, with over 95% and nearly 90% disposing of expired solid and liquid medications, respectively, via household waste. Notably, 96.1% of participants reported never receiving education on proper medication disposal. While 47.3% of respondents recognized the environmental impact of improper medication disposal, 46.9% agreed on the need for a strategy to retrieve unused or expired medications. Overall, 68.4% of respondents demonstrated poor perceptions about safe medication disposal practices. Significant associations were found between gender (χ
conclusionThe findings highlight the urgent need for public education, awareness campaigns, and policy reform to promote proper disposal of unused and expired medications in Ibadan, Nigeria.
