Influence of Ward Noise on Emotional State and Sleep Quality in Patients with Ventilator-induced Diaphragmatic Dysfunction.
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
objectivesThis study aimed to investigate the effect of noise control care on emotional state and sleep quality in patients with ventilator-induced diaphragmatic dysfunction (VIDD).
methodsThis retrospective study analysed 147 patients with VIDD between January 2023 and December 2023. Patients were grouped based on their admission period as follows: the standard care group (n = 63) comprised patients who received standard care in conventional wards between January 2023 and June 2023, whereas the noise control group (n = 84) included patients treated between July 2023 and December 2023 who additionally received noise reduction measures. Outcome measurements included Hamilton Anxiety Rating Scale (HAMA) and Hamilton Depression Rating Scale (HAMD) scores at baseline and Day 7. Other indicators included environmental sound levels (LAeq, LAmin and LAmax); Richards-Campbell Sleep Questionnaire (RCSQ) scores; haemodynamic measurements; duration of mechanical ventilation (MV) and incidence of delirium and hospital length of stay.
resultsBoth groups showed comparable baseline characteristics. The noise control group experienced significantly lower noise levels at daytime and nighttime than the standard care group (P < 0.001). Both groups demonstrated improved HAMA and HAMD scores by Day 7, but the noise control group showed significantly greater reductions than the standard care group (P < 0.001). RCSQ scores were significantly higher in the noise control group across all five domains and total score (P < 0.001). The noise control group exhibited improved haemodynamic stability with significantly reduced heart rate and blood pressure on Day 7 (P < 0.001). A significantly lowered incidence of delirium was observed in the noise control group (10.71% vs. 25.40%, P < 0.05), accompanied with a shortened duration of MV (P < 0.001) and hospital length of stay (P < 0.05).
conclusionNoise control was associated with reduced anxiety and depression, improved sleep quality and superior clinical outcomes in patients with VIDD.
