Incidence of residual bacterial contamination of transvaginal ultrasound probes.
Article in Journal of medical ultrasonics (2001), 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
purposeThe aim of the study was to investigate if ultrasound probes are reusable medical devices that risk becoming contaminated after a patient examination in Japan.
methodsThe level of bacterial contamination on transvaginal ultrasound (TVU) probes following current routine probe cleaning at a university hospital (site A) and a clinic (site B) in Japan was investigated.
resultsA total of 98.1% of probes were found to be contaminated at site A (median CFU 40, IQR 10, 132.5) and 94.1% were found to be contaminated at site B (median CFU 50, IQR 20, 85). Of the contaminated probes, 52.9% at site A and 64.6% at site B harbored potentially pathogenic bacteria including methicillin-resistant Staphylococcus aureus (MRSA).
conclusionThese findings suggest that there is a high rate of ultrasound probe residual bacterial contamination in Japan.
