Effects of Noise Exposure in Emergency Resuscitation Rooms on Cognitive Function and Hyperalgesia in Patients with Trauma: A Retrospective Study.
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
objectiveTo analyse the effects of noise exposure in emergency resuscitation rooms (ERRs) on cognitive function and hyperalgesia in patients with trauma.
methodsClinical data from 110 patients with trauma who were treated in the ERR of Suizhou Central Hospital between June 2022 and July 2023 were retrospectively analysed. Participants were divided into the following two groups on the basis of real-time noise monitoring: the high-noise-exposure (n = 85) and low-noise-exposure (n = 25) groups. Neuron-specific enolase (NSE), brain-derived neurotrophic factor (BDNF), homocysteine (Hcy), the Mini-Mental State Examination (MMSE), and the Montreal Cognitive Assessment (MoCA) were used to measure cognitive performance. Mechanical pain threshold and serum nerve growth factor (NGF), substance P (SP), calcitonin gene-related peptide (CGRP) and 5-hydroxytryptamine (5-HT) levels were applied to assess hyperalgesia. Pearson correlation was employed to investigate the connections between noise levels and outcome factors.
resultsThe high-noise-exposure group demonstrated significantly lower MMSE scores, MoCA scores and serum BDNF levels but higher serum NSE and Hcy levels compared with the low-noise-exposure group (P < 0.05). Additionally, compared with the low-noise-exposure group, the high-noise-exposure group exhibited larger mechanical hyperalgesia areas around incisions and on the volar forearm, as well as elevated serum CGRP, NGF and SP levels, while showing reduced mechanical pain thresholds and lower serum 5-HT levels (P < 0.05). Pearson analysis revealed that noise exposure values had negative correlations with mechanical pain threshold, MMSE and MoCA scores and serum BDNF and 5-HT levels (r < 0, P < 0.05) but positive correlations with mechanical hyperalgesia area and serum CGRP, NSE, Hcy, NGF and SP levels (r > 0, P < 0.05).
conclusionHigh noise exposure in ERRs may be associated with cognitive dysfunction and hyperalgesia in patients with trauma. Clinical management should recognise and control noise levels in these settings.
