Description of Noise Levels in a Pharmacy Department at a University Hospital.
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
objectiveFew data are available regarding noise levels in hospital pharmacies. This study mainly aimed to assess noise levels in different areas and during various activities in the pharmacy department of a tertiary care hospital affiliated with Université de Montréal in Canada and identify potential noise sources. MATERIALS AND
methodsThis cross-sectional descriptive study was conducted in the pharmacy department of Centre Hospitalier Universitaire (CHU) Sainte-Justine. A convenience sample of 30 sites was established to encompass various activities. Noise levels were measured with a sound level meter for three types of activity: office activities, storage, and drug preparation. Noise measurements were conducted for a 1-day period at each site.
resultsThe average noise level ranged from 41.9 ± 3.4 dBA to 71.4 ± 0.4 dBA during the day and from 37.5 ± 0.4 dBA to 71.2 ± 0.1 dBA at night. The levels were 50.9 ± 5.6 dBA in offices, 58.0 ± 5.8 dBA in storage areas, and 63.9 ± 9.2 dBA in drug preparation areas. Considering noise distribution by percentile, the L10 ranged from 43.7 to 71.7 dBA, the L50 from 37.8 to 71.3 dBA, and the L90 from 37.2 to 71.1 dBA.
conclusionAverage noise levels varied widely within the pharmacy department of the studied hospital, and a substantial proportion of it could be due to the building's ventilation system.
