High efficiency of 70% isopropanol in reducing microbial contamination on healthcare workers' smartphone surfaces: a pre-post study in Peru.

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
introductionPoor cleaning practices for healthcare workers' mobile phones can promote microbial contamination, posing a latent risk of infections for patients. Despite widespread mobile phone use in healthcare environments, evidence on the effectiveness of disinfection methods in low and middle-income countries remains limited.
objectiveTo evaluate the disinfectant capacity of 70% isopropanol on the surface of healthcare workers' smartphones in a Peruvian hospital in 2023.
methodsWe designed a pre-post study to collect demographic, occupational, and phone usage information, along with microbiological culture analysis results before and after cleaning with 70% isopropanol.
resultsWe evaluated 178 mobile phones from healthcare workers, 90.5% (95%CI: 85.1-94.0%) of which showed microbiological contamination. The most frequently isolated microorganism was Staphylococcus aureus (41.0%), followed by Enterococcus sp. (14.9%) and Staphylococcus epidermidis (9.9%). Antibiogram analysis revealed high resistance rates to ampicillin. No factors were associated with microbial contamination on phones. A significant reduction in microbiological contamination was observed (90.4% to 14.0%, p < 0.001) after cleaning with 70% isopropanol. Colony counts significantly decreased from 73.4 ± 31.8 CFU/cm
conclusionThe disinfectant capacity of 70% isopropanol on healthcare workers' smartphone surfaces is highly effective, resulting in an approximately fivefold reduction in contamination rates.
