Prevalence of atypical pathogens in patients with severe pneumonia: a systematic review and meta-analysis.
Synthesis in BMJ open, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 21 papers, 1 of them a synthesis 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
objectivesWe aimed to summarise the prevalence of atypical pathogens in patients with severe pneumonia to understand the prevalence of severe pneumonia caused by atypical pathogens, improve clinical decision-making and guide antibiotic use.
designSystematic review and meta-analysis. DATA SOURCES: PubMed, Embase, Web of Science and Cochrane Library were searched through November 2022. ELIGIBILITY CRITERIA: English language studies enrolled consecutive cases of patients diagnosed with severe pneumonia, with complete aetiological analysis. DATA EXTRACTION AND SYNTHESIS: We conducted literature retrieval on PubMed, Embase, Web of Science and The Cochrane Library to estimate the prevalence of
resultsWe included 75 eligible studies with 18 379 cases of severe pneumonia. The overall prevalence of atypical pneumonia is 8.1% (95% CI 6.3% to 10.1%) In patients with severe pneumonia, the pooled estimated prevalence of
conclusionsIn severe pneumonia, atypical pathogens are notable causes, especially PROSPERO REGISTRATION NUMBER: CRD42022373950.
