Detection of Group A Beta Hemolytic Streptococci Species, emm, and Exotoxin Genes Isolated from Patients with Tonsillopharyngitis.
Article in Current microbiology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 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
Group A Beta Hemolytic Streptococci (GAS) is the most critical human pathogen that leads to tonsillopharyngitis. The aims of this study were to identify GAS isolates and to determine emm typing, the coverage rate of available vaccines, and the distribution of superantigen gene profiles. 15 GAS isolates were isolated from throat cultures of 200 patients with tonsillopharyngitis, who were admitted to Canakkale Health Application and Research Hospital between October 2017 and May 2018. Identification of the isolates was performed by conventional methods and 16S rRNA sequence analysis. emm typing and exotoxin profiling of the isolates were performed by polymerase chain reaction. 7.5% GAS was detected in 200 patients. All the GAS isolates were identified as S. pyogenes. emm typing can be carried out in 13 S. pyogenes isolates. emm89 (33.3%), emm44 (20%), emm6 (13.3%), emm84 (6.7%), emm1 (6.7%), and emm18.1 (6.7%) were found to be six emm types. The coverage rate of S. pyogenes strains for 26-valent vaccine was 61.5% and for the 30-valent vaccine 84.6%. The most common exotoxin was speB (86.7%), followed by speC (60%), speF (33.3%), ssa (26.7%), speA (20%), speM (20%), speJ (13.3%), speL (6.7%), and speI (6.7%). As a result of determining the emm types of S. pyogenes species in Canakkale, it was concluded that the potential of 30-valent vaccine should be considered in Turkey and development of vaccines containing exotoxin types may be beneficial.
