Microbiological contamination in home continuous positive airway pressure (CPAP) devices. Study protocol.
Article in MethodsX, 2026. 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
Home mechanical ventilation is crucial for treating conditions such as obstructive sleep apnea, and its use has increased exponentially. A possible link exists between poor equipment hygiene and the risk of respiratory infections, due to healthcare-related practices; however, the exact effect is unknown. The aim of this study is to determine the level of bacterial and fungal contamination in home continuous positive airway pressure (CPAP) devices. This prospective, cross-sectional study will be conducted at the Burgos University Hospital Complex (CAUBU), Spain. Twenty-five patients undergoing home CPAP treatment for at least six months will be recruited. Microbiological samples will be taken from each patient at critical points of the CPAP device: CPAP housing, tubing, internal filter, interface, and humidifier. Analyses will be performed at the CAUBU Microbiology Department, which is certified under UNE-EN ISO 9001:2015. In addition to microbiological analysis, clinical variables and determinants of patient health will be collected to study potential factors associated with contamination. It is known that 30% of healthcare-associated infections are preventable, so this study aims to improve prevention strategies, health education, and nursing care to reduce the risk of pathogenic contamination related to home respiratory therapy.
