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.

2 · The registry

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

backgroundMycoplasma Pneumoniae (M. pneumoniae) is a common cause of respiratory tract infections (RTIs), especially in children. Combined diagnostic techniques have provided more reliable information about the epidemiology of infections by this pathogen. The relationship between M. pneumoniae RTIs and climatic conditions is not well documented in the literature.

aimsTo study the epidemiology of M. pneumoniae infections in hospitalized children with RTIs and its association with meteorological factors.

methodsSamples were obtained from children with RTIs and tested for M. pneumoniae by PCR and ELISA. Meanwhile, meteorological factors were recorded.

resultsM. pneumoniae was identified in 11.02% of the 8,157 specimens. There were significant differences among the annual distribution of infections (χ(2) =130.13, P<0.0001) and among different seasons (χ(2) =93.59, P<0.0001). Of the total number of patients with M. pneumoniae infections, 14.5% were infected with more than one pathogen. M. pneumoniae infection strongly correlated with mean temperature. Children with a single M. pneumoniae infection had significantly higher neutrophil percentages and CRP levels than children with co-infections.

conclusionsM. pneumoniae is one of the most commonly held pathogens, according to the 5-year surveillance. M. pneumoniae infection has its own epidemic season, especially in the summer. Mean temperature is the main meteorological factor affecting the epidemiology of M. pneumoniae infections.
