The prevalence of respiratory pathogens in adults with community-acquired pneumonia in an outpatient cohort.
Article in Infection and drug resistance, 2019. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 15 papers, 2 of them syntheses that pooled 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeCommunity-acquired pneumonia is a common illness worldwide. In adults, community-acquired bacterial pneumonia has been well studied, but viral pneumonia is less well understood. We designed this study to identify respiratory pathogens, including common pneumonia-causing bacteria, viruses and atypical pneumonia pathogens, using reverse transcription-polymerase chain reaction. PATIENTS AND
methodsWe conducted a retrospective study of outpatients with community-acquired pneumonia at the Fever Clinic of Peking University Third Hospital. We collected sputum or throat swabs from patients diagnosed with community-acquired pneumonia. Multiplex real-time reverse transcription-polymerase chain reaction was performed for 20 pathogens, including 9 viruses, 3 atypical pathogens and 8 bacteria.
resultsThere were 232 outpatients enrolled in our study, and 153 patients (65.9%) had positive test results, of which 26.7% were viruses, 19.4% were atypical pathogens and 19.8% were bacteria. Mycoplasma pneumoniae infection was detected at the highest frequency (19.0%), exceeding Streptococcus pneumoniae infection. The most commonly identified viral pathogens were IFVs (15.1%), PIVs (3.4%) and RhV (2.6%). The most commonly identified bacteria were Streptococcus pneumoniae (9.1%), Haemophilus influenza (6.5%) and Klebsiella pneumoniae (2.6%).
conclusionOur study suggests that viruses were commonly detected in outpatients with CAP, and IFVs were the most common viruses, especially during flu season. Patients with viral infection were prone to viral-bacterial coinfection. Mycoplasma pneumoniae was the leading pathogen in the outpatients with CAP. Viral infection occurs in a large number of outpatients with CAP, and it should receive greater attention in clinical work.
