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
This study examines the mediating roles of employee involvement and quality culture in the relationship between Total Quality Management (TQM) practices and safety performance within the context of digital transformation, the Industrial Internet of Things (IIoT), and Industry 4.0. A quantitative cross-sectional survey was conducted among 100 employees from manufacturing and service organizations in Saudi Arabia. Data were collected using an online questionnaire comprising nine items measuring four constructs: TQM practices, employee involvement, quality culture, and safety performance. Responses were measured using a five-point Likert scale. Data analysis included reliability assessment using Cronbach's alpha, evaluation of common method variance through Harman's single-factor test, and mediation analysis using Hayes' PROCESS macro. Simple mediation models (Model 4) and a serial mediation model (Model 6) were estimated using 5,000 bootstrap samples and 95% bias-corrected confidence intervals. The results indicate that both employee involvement and quality culture significantly mediate the relationship between TQM practices and safety performance. Employee involvement demonstrated a significant indirect effect [0.17, 95% CI (0.06, 0.33)], while quality culture showed a stronger indirect effect [0.34, 95% CI (0.24, 0.49)]. Furthermore, the serial mediation pathway linking TQM practices, employee involvement, quality culture, and safety performance was significant [indirect effect = 0.11, 95% CI (0.03, 0.20)]. Gap analysis revealed that employee voice received the lowest mean score (3.64/5), suggesting limited opportunities for employees to express opinions and participate in decision-making processes. The findings suggest that employee involvement and quality culture are important mechanisms through which TQM practices are associated with improved safety performance, with quality culture emerging as the stronger mediator. However, the results should be interpreted cautiously because the quality culture construct demonstrated low internal consistency (Cronbach's
