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

backgroundCommunity-acquired pneumonia (CAP) frequently requires empirical antibiotic treatment owing to its nonspecific symptoms and the need for urgent intervention. Understanding the epidemiology of patients hospitalized with CAP at a regional level is essential for developing effective treatment strategies. Therefore, this study aimed to assess the epidemiological and clinical characteristics of CAP in patients admitted to a tertiary care hospital in Korea.

methodsUtilizing a common data model, we selected patients aged 18 years and older who were admitted to Seoul National University Bundang Hospital from January 2005 to July 31, 2019. These patients presented with pneumonia-related symptoms, such as fever or a respiratory symptom, and had a pneumonia diagnosis code within 7 days of admission. The medical records of these patients were retrospectively reviewed. Patients without pneumonia, who had been hospitalized within 14 days before the start of the study, and those with pulmonary tuberculosis were excluded.

resultsOut of 7,147 patients with pneumonia-related symptoms, 4,083 were included in the study. The mean age of the patients was 70.1 years, with 66.7% being male. The most prevalent comorbidities were chronic lung disease (42.6%), malignancy (24.4%), and immunocompromised conditions (26.5%).

conclusionIn patients hospitalized with CAP in a tertiary care center in this study, gram-negative bacteria and the traditionally known
