Antimicrobial susceptibility testing of Neisseria gonorrhoeae using a phenotypic-molecular assay and lyophilized antimicrobials.
Article in Diagnostic microbiology and infectious disease, 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Gonorrhea is an urgent global public health threat as Neisseria gonorrhoeae (Ng) has progressively developed resistance to all antibiotics commonly used for treatment. Surveillance of antimicrobial susceptibility trends is critical to monitor the emergence and spread of antimicrobial resistance. The gold standard methods for antimicrobial susceptibility testing (AST) of Ng are laborious and time-consuming. We evaluated a phenotypic molecular approach, involving a short cultivation step and quantitative PCR, with lyophilized antimicrobials to characterize antimicrobial susceptibility in Ng. There was excellent concordance between AST performed with liquid and lyophilized ciprofloxacin, penicillin, and tetracycline using the pheno-molecular assay, following a 4-hour incubation step. The categorical agreement between the pheno-molecular assay and the gold standard AST results was 92.4% for characterization of antimicrobial susceptibility. Essential agreement between the 2 methods was 91.9%. Characterization of ceftriaxone susceptibility in Ng using the pheno-molecular assay required a 6-hour incubation step.
