A Study on the Correlation between Noise and Sleep Disorders in the Emergency Observation Ward for Elderly Patients.

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
objectiveThis study aimed to investigate the relationship between objective nighttime noise exposure and sleep quality in elderly patients under emergency observation and to verify whether higher nighttime noise levels are an independent factor contributing to poorer sleep quality after controlling for multiple confounding factors.
methodsThe single-center retrospective observational study consecutively enrolled 150 elderly patients (age ≥ 65 years) who were under observation in the emergency department of Zhejiang Sian International Hospital for ≥ 24 h between 31 December 2024 and 31 December 2025. Noise data for the first full night (22:00 to 06:00 the next day) during the observation period were obtained using a fixed automatic environmental noise monitor, with nighttime equivalent sound level (LAeq,8h) as the core exposure indicator. Sleep quality was measured with the Richards-Campbell Sleep Questionnaire (RCSQ), and an RCSQ score < 50 was defined as having a sleep disorder. Covariates included age, sex, disease severity (Modified Early Warning Score, MEWS), pain intensity (Numerical Rating Scale, NRS), anxiety status (Self-Rating Anxiety Scale, SAS), observation duration, and sedative-hypnotic drug use. Pearson correlation analysis was used to examine the relationship between noise and sleep quality, and multiple linear regression analysis was used to adjust for confounding factors and test the independent effect of LAeq,8h on RCSQ score.
resultsCorrelation analysis revealed a significant negative association between LAeq,8h and RCSQ score ( r = -0.431, P < 0.001). After adjusting for all covariates, multiple linear regression confirmed that LAeq,8h remained an independent predictor of a lower RCSQ score (unstandardized B = -0.313, 95% CI: -0.434 to -0.193, standardized β = -0.404, t = -5.130, P < 0.001). In logistic regression, each 1 dB increase in LAeq,8h was associated with 8% higher odds of sleep disorder (OR = 1.08, 95% CI: 1.03 to 1.13, P = 0.002).
conclusionIn elderly patients under emergency observation, higher LAeq,8h is independently associated with poorer sleep quality.
