Synergistic Impact of Nasal Irrigation and Health Education in Reducing Chronic Rhinosinusitis Among Cement Plant Workers: a Randomized Controlled Trial.

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: Chronic rhinosinusitis (CRS) is a prevalent and debilitating condition among industrial workers exposed to occupational hazards such as dust and chemical irritants. Despite its significant impact on quality of life and productivity, evidence-based interventions for occupational CRS remain limited. Objective: This study evaluates the effectiveness of combined health education and nasal irrigation in reducing CRS symptoms among direct labor workers at the Hai Phong Cement Plant, Vietnam. Methods: A randomized controlled trial was conducted from 2014 to 2015, involving 90 workers diagnosed with CRS. Participants were randomly assigned to an intervention group (n=45), receiving nasal irrigation kits and training, or a control group (n=45), receiving health education only. Health education sessions focused on improving knowledge, attitudes, and practices (KAP) related to CRS prevention. Nasal irrigation involved twice-daily rinsing with 0.9% saline solution. Outcomes were assessed using structured questionnaires, clinical examinations, and the Intervention Effectiveness Index (HQCT). Results: The health education intervention significantly improved KAP scores, with a 2967% increase in positive attitudes and an 847% improvement in understanding preventive measures. Nasal irrigation demonstrated substantial efficacy, reducing moderate nasal discharge by 58% and nasal congestion by 1600%. Objective findings revealed a 1657% increase in workers reporting no nasal cavity discharge and a 158% improvement in nasal mucosal health. After six months, 60% of the nasal irrigation group reported "good" improvement, compared to 11.1% in the control group (p < 0.05). Conclusions: This study highlights the synergistic potential of health education and nasal irrigation in managing occupational CRS. Nasal irrigation, in particular, emerged as a highly effective, low-cost intervention for alleviating CRS symptoms in high-risk industrial settings. These findings underscore the importance of integrating non-pharmacological approaches into occupational health programs to safeguard respiratory health among workers exposed to environmental hazards.
