Invasive group A streptococcal infection in children: clinical manifestations and molecular characterization in a French pediatric tertiary care center.
Article in European journal of clinical microbiology & infectious diseases : official publication of the European Society of Clinical Microbiology, 2010. 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
Invasive group A streptococcal (GAS) infections have a broad and evolving clinical spectrum, associated with various GAS genotypes and/or virulence factors that are only poorly described in children. We aimed to assess the clinical and molecular characteristics of invasive GAS infections in 28 children admitted from 2000 to 2007 at a large French pediatric tertiary care center. The GAS isolates were characterized molecularly by emm-typing and by the determination of the main virulence factors: speA, speB, speC, smeZ-1, ssa, sic, and silC. The median age of the children was 2.9 years. Osteoarticular infection (OAI) was the main clinical manifestation (n=15/28, 53%). emm-1 predominated (n=10/28), followed by emm-12, 3, and 4. No significant correlation was found between emm type and clinical manifestations, but emm-1 predominated in cases of OAI (n=7/15) and was associated with speA, speB, smeZ-1, and sic virulence factor genes. In this pediatric study, we describe a predominance of OAI associated with emm-1 GAS. Further larger international pediatric studies, including host immunity evaluation, are needed in order to better assess the pathogenesis of GAS infection in children.
