Ultraviolet-C Light Emitter as a Method for Reducing Bacterial Contamination of Ophthalmic Instruments.
Article in Journal of ophthalmology, 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
Background: To assess the efficacy of an ultraviolet light type C (UVC) emitter in reducing bacterial load in common surgical equipment used during in-office ophthalmological procedures. Methods: We used 7 steam-sterilized lid speculums. The first one was the negative control. The second was left unprotected in a high-traffic area for 24 h before being cultivated. Lid speculums 3 to 7 were contaminated with a strain of Results: We analyzed 27 bacterial cultures. After 24 h, lid speculum 2 showed growth of a single colony of Conclusions: This exploratory laboratory study suggests that, after 5 min of UVC exposure using a commercially available emitter, no recoverable bacteria were detected on lid speculums under these experimental conditions. Although spores, fungi, and viruses were not evaluated, these findings suggest that UVC irradiation may be a feasible approach for reducing bacterial contamination of reusable instruments during in-office ophthalmic procedures.
