In-Store Cosmetic Testers Harbour Resistant Bacteria: A Pilot Survey of Microbial Contamination and Antimicrobial Susceptibility in Portuguese Pharmacies.
Article in Microorganisms, 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
Cosmetic testers in community pharmacies may act as a source of microbial transmission, but their microbiological safety remains poorly characterised. This study assessed microbial contamination of 42 cosmetic testers (eight product categories) from community pharmacies in northern Portugal using culture-based methods, identification and Kirby-Bauer disk diffusion. We characterised the antimicrobial susceptibility of the recovered isolates. Microbial growth was detected in 25/42 testers (59.5%), with polymicrobial contamination in 16.7% of samples. Out of the 25 positive growth products, 33 characterised bacterial isolates were yielded.
