1 · What the graph read from it

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.

2 · The registry

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

Introduction: The growing amount of electronic waste (e-waste) creates serious occupational safety and health risks worldwide. This study aimed to develop and psychometrically validate the E-Waste Integrated Safety and Health Effects (E-WISE) questionnaire to evaluate knowledge, attitudes, perceptions, safety practices, and health effects among formal e-waste recovery workers in Malaysia. Methodology: The E-WISE domains were identified through a literature review and expert verification. The questionnaire was developed in Malay using a multistage questionnaire development framework. Content validation by six experts ensured relevance and accuracy, while face validation with ten e-waste workers assessed clarity. A pretest evaluated the questionnaire's practicality. Item analysis for the Knowledge domain examined difficulty and discrimination indices. Exploratory Factor Analysis using Principal Axis Factoring and internal consistency reliability analyses were performed to evaluate the questionnaire's construct structure and internal stability. Results: A total of 76 e-waste workers from 18 licensed recovery facilities across eight Malaysian states participated. Content and face validation showed excellent relevance and clarity (S-CVI/Ave = 0.99-1.00; S-FVI/Ave = 0.97-1.00). Item analysis for the Knowledge domain indicated acceptable difficulty ( Conclusion: The E-WISE questionnaire demonstrated strong validity and reliability in assessing occupational safety and health among e-waste recovery workers. The instrument provides a structured and context-specific tool for evaluating occupational safety culture, safety practices, and health effects within formal e-waste recovery facilities in Malaysia and may support future occupational health monitoring and intervention efforts.
