Effectiveness of processing laryngoscopes used in surgical patients undergoing orotracheal intubation.
Article in Revista brasileira de enfermagem, 2025. 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
objectivesto evaluate the effectiveness of processing laryngoscopes used in surgical patients undergoing orotracheal intubation.
methodsthis was a descriptive, analytical, quantitative study conducted in a public hospital in Minas Gerais, Brazil, in two phases: assessment of the protein test and the persistence of simulated microorganisms on laryngoscopes. Data were analyzed using descriptive statistics and the Wilcoxon Signed Rank test.
resultsa total of 48 samples were analyzed, distributed across 24 protein tests, 12 fluorescence analyses, and 12 visual inspections of the laryngoscope conditions. There was a significant reduction in protein levels after processing (z = -2.58, p < 0.010), with a moderate effect size (r = 0.74). However, all samples failed the qualitative assessment, as protein levels exceeded the acceptable limit of 1 µg/cm2.
conclusionsthere was a reduction in simulated microorganisms. However, all protein tests failed, indicating the ineffectiveness of laryngoscope disinfection.
