Article in PloS one, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT04126304 (Multi-center Investigation and Study of Mycoplasma Pneumoniae Infection and Macrolide Drug Resistance in Outpatient and In-hospital Pediatric Acute Respiratory Diseases Illness in China), which is not on this map. Cited by 60 papers, 1 of them a synthesis that pooled it.

1 · What the graph read from it

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.

Abstract

backgroundMycoplasma pneumoniae is a common cause of community-acquired pneumonia in older children. Pulmonary and extra-pulmonary symptoms associated with M. pneumoniae infection are reported. M. pneumoniae is mainly epidemic in Denmark with the recurrence every 4-7th year.

aimsRetrospectively, to describe the epidemiology and clinical features, in infants and children, during the M. pneumoniae epidemic in 2010 and 2011.

methodsAll children under the age of 16 that were tested for M. pneumoniae during the period 01.02.2010-31.01.2012 were included. Medical charts, as well as radiological findings, were reviewed for all children with M. pneumoniae. A post-hoc analysis of viral co-infections was done on part of the cohort.

results134 of 746 children were tested positive for M. pneumoniae by PCR or serology. Positive tests were found in 65% of children seven years and older, in 30% of 2-6-year-olds and 4% of infants (less than two years of age). Viral co-infection was found in 27% of the tested samples. The clinical presentation was a cough, asthma-like symptoms and low-grade fever. Extra-pulmonary symptoms were common and presented as nausea/vomiting by 33% of the children and skin manifestations by 25%. 84% of the children had a chest x-ray taken, and there were positive radiological findings in 94% of these.

conclusionM. pneumoniae also affected infants and young children and symptoms were similar to infections with respiratory viruses, but severe LRTI were also seen. During an up-coming epidemic, assessment of extra-pulmonary manifestations can be helpful when diagnosing M. pneumoniae infections.
