Effect of noise and green space exposure on depression, anxiety and stress among the Lebanese population.
Article in PloS one, 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
backgroundEnvironmental exposure significantly influences mental well-being. Green spaces offer psychological benefits, while noise exposure is a recognized environmental stressor. However, their effects on mental health outcomes such as depression, anxiety, and stress remain underexplored in Lebanon. This study investigates the influence of green space and noise exposure on mental health in the Lebanese population.
methodsA cross-sectional study was conducted using an online survey distributed across the Lebanese population. A total of 653 participants aged 18-65 years completed the questionnaire, which assessed socio-demographics, green space exposure, noise exposure, and mental health using the Arabic versions of the validated scales for depression (PHQ-9), anxiety (GAD-7), and stress (PSS-10). Data was analyzed using SPSS version 25.
resultsHigher green space exposure-such as proximity to greenery, views of natural environments, and more frequent visits-was significantly associated with lower levels of depression, anxiety, and stress (p < 0.05). Conversely, greater noise exposure at home or work, and symptoms such as sleep disturbance, irritability, or difficulty concentrating due to noise, were significantly associated with higher scores across all three mental health domains (p < 0.001). Multiple linear regression showed that some noise-related symptoms were consistently associated with higher depression, anxiety, and stress.
conclusionsEnvironmental exposures play a critical role in shaping the mental health. Increasing access to green spaces and reducing noise pollution may serve as effective public health interventions to decrease levels of depression, anxiety, and stress among Lebanese residents. Urban planning and public policy should integrate these findings into mental health promotion strategies.
