Impact of Noise Levels of the Dialysis Machine Alarm on Patient Anxiety.

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
INTRODUCTION AND
backgroundHemodialysis machine alarms are warning noises, which are essential for patient safety, but the psychological impact of these alarms is often overlooked. This study aims to assess the relationship between hemodialysis machine alarm noise levels and anxiety among patients undergoing thrice weekly hemodialysis.
methodsThis observational, cross-sectional, analytical study was conducted on 53 participants who were undergoing hemodialysis. A Benetech GM1351 digital sound-level meter was used to measure the noise level of hemodialysis machine alarms. Socio-demographic data and Hamilton Anxiety Rating Scale (HAM-A) were used for data collection.
resultsThe range of noise level of hemodialysis machine alarms was detected from 48.5 to 77.8 dB(A). The study findings revealed that hemodialysis patients who are exposed to high intensity of the hemodialysis machine alarm have a negative impact on anxiety level in the hemodialysis unit. Females and participants with a higher level of education have higher anxiety levels.
conclusionHigher hemodialysis machine alarm noise had a significant impact on hemodialysis patients' anxiety. In addition, sex and educational status became predictors of anxiety. Future interventional research, such as alarm management protocols and tailored education programs to reduce anxiety among dialysis patients due to alarms, can provide meaningful insights.
