Relationship between Environmental Noise Exposure in Hospitals and Respiratory Infections in Elderly Individuals with Cognitive Decline: A Retrospective Analysis.
Article in Noise & health. 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
backgroundHospital noise pollution poses major health risks for elderly urban residents, particularly those with cognitive decline (Mini-Mental State Examination ≤24). While noise may affect respiratory health through inflammation and sleep disruption, its direct association with infection rates in this vulnerable population remains unclear.
methodsThis retrospective cohort study enrolled 92 elderly patients with cognitive decline. Participants were stratified by World Health Organization guidelines into high-noise [night equivalent sound level (Lnight) ≥55 dB, n = 46] and low-noise (Lnight < 55 dB, n = 46) groups. Annual respiratory infection rates, inflammatory markers (high-sensitivity C-reactive protein, interleukin-6, and neutrophil-to-lymphocyte ratio), Pittsburgh Sleep Quality Index, lung function (forced expiratory volume in 1 s/forced vital capacity%), blood pressure, and heart rate variability were assessed. Spearman's rank correlation was used to evaluate the strength of the association between Lnight and each of the detection indicators. A multivariate logistic regression model was employed to analyze the relationship between each factor and the outcome of respiratory tract infection.
resultsCompared with the low-noise group, the high-noise group demonstrated significantly elevated inflammatory markers, poorer sleep quality, higher systolic blood pressure, and reduced lung and autonomic functions (all P < 0.05). High noise exposure significantly increased respiratory infection risk (odds ratio = 1.092, 95% confidence interval: 1.009-1.182; P < 0.005).
conclusionResults suggest that long-term environmental noise exposure is associated with an increased risk of respiratory tract infections in the elderly with cognitive decline. Cognitive impairment may aggravate this association to some extent by affecting behavioral adaptation and physiological stress responses.
