Society for Maternal-Fetal Medicine Special Statement: Reducing the risk of transmitting infection during ultrasound examination-Updated 2026.
Article in Pregnancy (Hoboken, N.J.), 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
Ultrasound examinations have the potential to transmit infections between individuals. The risk can be reduced by following certain well-described procedures to clean and disinfect ultrasound transducers between examinations. However, surveys have shown widespread lapses in the cleaning and disinfection of transducers and other equipment. In 2020, the Society for Maternal-Fetal Medicine (SMFM) published a Patient Safety Guideline focused on reducing the risk of transmitting infection in transvaginal examinations, with emphasis on selection of high-level disinfectants with proven efficacy against human papillomavirus (HPV), choice of transducer covers with documented low leakage rates, and cautions regarding multiuse containers of coupling gel. In this article, SMFM presents updated guidelines with an expanded scope that includes transabdominal examinations and ultrasound-guided percutaneous and intraoperative procedures. Other updates include a list of newer high-level disinfection systems and citation of recent literature on virucidal efficacy of ortho-phthalaldehyde against HPV. The guidelines are based on the Spaulding classification of infection risk and are aligned with recommendations from the American Institute of Ultrasound in Medicine, the Centers for Disease Control and Prevention, and the US Food and Drug Administration.
