Etiology of community-acquired pneumonia in adults: a systematic review.
Review in Pneumonia (Nathan Qld.), 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT06716099 (Clinical Characteristics and Outcome of Patients With Community Acquired Pneumonia), which is not on this map. Cited by 130 papers, 6 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.

Abstract
backgroundThe etiology of community-acquired pneumonia (CAP) has evolved since the beginning of the antibiotic era. Recent guidelines encourage immediate empiric antibiotic treatment once a diagnosis of CAP is made. Concerns about treatment recommendations, on the one hand, and antibiotic stewardship, on the other, motivated this review of the medical literature on the etiology of CAP.
methodsWe conducted a systematic review of English-language literature on the etiology of CAP using methods defined by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We searched PubMed using a combination of the keywords 'pneumonia', 'CAP', 'etiology', 'microbiology', 'bacteriology', and 'pathogen'. We examined articles on antibiotics that were develop to treat pneumonia. We reviewed all 'related articles' as well as studies referenced by those that came up in the search. After we excluded articles that did not give sufficient microbiological data or failed to meet other predetermined criteria, 146 studies remained. Data were stratified into diagnostic categories according to the microbiologic studies that were done; results are presented as the percentage in each category of all cases in which an etiology was established.

conclusionThe results of this study justify current guidelines for initial empiric treatment of CAP. With pneumococcus and
