Effectiveness of the Healthy Hearing Promoting Program (HHPP) among workers in large-scale industries: A randomized controlled trial in central Thailand.
Article in Belitung nursing journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Background: Noise-induced hearing loss remains a significant occupational health concern in industrial settings. Adherence to protective behaviors among workers remains suboptimal, leaving them at continued risk of hearing impairment. Strengthening hearing health promotion is therefore essential. Objective: To evaluate the effectiveness of the Healthy Hearing Promoting Program in promoting noise hazard protection behavior and maintaining hearing capacity among workers in large-scale industries. Methods: This single-blind parallel-group randomized controlled trial included 66 industrial workers from two large-scale factories in central Thailand, randomly assigned to an experimental group ( Results: There were no significant differences in baseline data between groups. The experimental group had significantly higher noise hazard protection behavior scores than the control group (F (1,64) = 41.67, Conclusion: The program significantly improved noise hazard protection behaviors but no significant between-group differences in hearing capacity were demonstrated. The findings provide preliminary evidence to support occupational health nurses in developing and implementing theory-driven, multilevel hearing conservation interventions aimed at improving noise hazard protection behaviors among workers in large-scale industries. Trial Registry Number: Thai Clinical Trials Registry (TCTR20251128006).
