Noise Produced by Neonatal Ventilators Inside and Outside of the Incubators.
Article in Respiratory care, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundInsufficient data are available about the noise produced by modern neonatal ventilators. We aimed to measure their noise under different ventilatory modes and parameters.
methodsThis was a bench study measuring the noise produced by 9 neonatal ventilators set in conventional or high-frequency oscillatory ventilation (HFOV), nasal mask-delivered CPAP with variable- or continuous-flow configuration, or bi-level positive airway pressure (considered as noninvasive ventilation [NIV]). Conventional ventilation and HFOV were tested in 2 distinct settings with moderate or higher parameters. Sound measurements were performed inside and outside an incubator mimicking the clinical setting and using a high-end meter meeting the international ISO 226:2003 standard.
resultsFour ventilators remained below the internationally recommended safety threshold but only for measurements outside the incubator. Conventional ventilation (49.1 [3.4] dBA) and HFOV (56.3 [5.2] dBA) were the least and most noisy respiratory support technique, respectively. Noise was greater inside than outside the incubators (
conclusionsModern ventilators often produce relevant noise, independent of the respiratory support modality, with acceptable noise levels being measured only outside the incubator. Better results were achieved with Servo-u, VN500, and Fabian family devices.
