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
backgroundMobile phones are widely used by healthcare students during clinical training and may act as potential reservoirs for pathogenic microorganisms.
objectivesThis study aimed to investigate and evaluate the role of mobile phones as epidemiological factors in the transmission of microorganisms in medical and dental practice.
methodsA cross-sectional epidemiological and microbiological study was conducted between September 2025 and April 2026. A total of 125 mobile phones belonging to fourth-year dental students and fifth-year medical students were examined. Samples were collected from the entire phone surface and cultured on blood agar, eosin-methylene blue agar, and Candida chromogenic agar. Participants also completed a structured questionnaire assessing demographic characteristics, clinical experience, hand hygiene practices, and mobile phone use and cleaning habits.
resultsNo microbial growth was detected in 52.8% of samples on blood agar, while 44.8% showed growth below 10
conclusionsTouching mobile phones with contaminated gloves was significantly associated with microbial growth. These findings emphasize the need for targeted infection control education and stricter guidelines regarding mobile device use during clinical training.
