Noise as a risk factor in the delivery room: A clinical study.
Article in PloS one, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers.
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
introductionWe aimed to investigate whether noise in delivery rooms is associated with impaired performance of obstetric teams managing major (≥1000 mL) postpartum hemorrhage. MATERIAL AND
methodsWe included video recordings of 96 obstetric teams managing real-life major postpartum hemorrhage. Exposure was noise defined as the occurrence of sound level pressures (SPL) above 90 dB. The outcome was high clinical performance assessed through expert ratings using the TeamOBS-PPH tool.
resultsThe 23 teams unexposed to noise had a significantly higher chance of high clinical performance than the 73 teams exposed to noise: 91.3% (95% CI; 72.0-98.9) versus 58.9% (95% CI; 46.8-70.3) (p < 0.001). The results remained significant when adjusting for the following possible confounders: team size, non-technical performance, bleeding velocity, hospital type, etiology of bleeding, event duration and time of day. Typical sources of noise above 90 dB SPL were mother or baby crying, dropping of instruments, and slamming of cupboard doors.
conclusionNoise in delivery rooms may be an independent source of impaired clinical performance.
