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

objectivesAccurate estimates of the burden of vaccine-preventable community-acquired pneumonia (CAP) hospitalisations both overall and due to the most frequent and vaccine-preventable pathogens are needed to inform the use of respiratory vaccines in adults. DESIGN AND

settingThis was a prospective, population-based CAP surveillance study at three hospitals in Germany. All patients admitted with clinically suspected CAP were tested for

participantsIndividuals admitted to study hospitals within the surveillance period with suspected or confirmed diagnosis of pneumonia who provided informed consent. OUTCOME MEASURES: Radiologically confirmed (RAD) CAP.

resultsActive surveillance between 1 January 2021 and 30 June 2023 identified at the three study sites 4319 adults with RAD-CAP that met eligibility criteria, of which 1479 (34.2%) were enrolled and included in the analysis for pathogen distribution. The main reason for non-enrolment was the inability to provide informed consent. Incidence estimates were based on 1254 study-eligible individuals admitted at the largest study site. SARS-CoV-2,

conclusionsActive pneumonia surveillance reported a high burden of RAD-CAP hospitalisations in Germany, especially among older adults. The resurgence of CAP due to RSV,
