Comparative performance of commercial Amies transport media with and without charcoal for
Article in Germs, 2021. 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
introductionCulture is the only laboratory method that provides live gonococcal isolates for monitoring antimicrobial resistance. Many clinical settings do not have direct access to laboratories for the immediate processing of biological samples. Validated and quality-assured transport media are recommended to maintain the viability of
methodsIn total, 103 clinical samples were divided into two groups: 51 samples were stored in Amies agar gel medium containing charcoal and 52 samples were stored in agar gel medium without charcoal. All samples were stored at 4°C for 0.5-6 h and then transported in a thermo-protected box within 0.17-0.25 h to the laboratory of Ternopil Regional STI Clinic (Ukraine).
resultsThe recovery rate was significantly higher for charcoal-containing Amies medium than for charcoal-free Amies medium (86.27%, 44/51 vs. 59.62%, 31/52). A higher rate of specimens transported in charcoal-containing Amies medium was isolated within 24 h (84.31%, 43/51), whereas most isolates from charcoal-free Amies medium grew within 24 h (42.31%, 22/52) or 48 h (17.31%, 9/52). Growth beyond the first quadrant of the agar plate was registered for 59.09% (26/44) of charcoal-containing Amies samples, compared with only 19.35% (6/31) of charcoal-free Amies samples.
