Prognosis of Infective Endocarditis According to Clinical Characteristics, Economic Status, and Center Experience.
Article in Yonsei medical journal, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeInfective endocarditis (IE) is a life-threatening disease with high morbidity and mortality rates. However, the risk factors for mortality in these patients require further study. This study aimed to evaluate the association of clinical outcomes of IE with patients' clinical characteristics and economic status and treatment center experience using nationwide data. MATERIALS AND
methodsData were collected from the National Health Insurance System of South Korea. Patients diagnosed with IE between 2003 and 2018 were included. Baseline characteristics, treatment, and survival outcomes were analyzed.
resultsAmong the 8487 patients included, 6617 (78.0%) had native valve IE, 1678 (19.8%) had prosthetic valve IE, and 192 (2.3%) had cardiac device-related IE (CDRIE). In-hospital mortality was 12.1±2.8% (121.3 deaths per 1000 IE case-years). In the multivariate analysis adjusted for variables significant in the univariate Cox regression, CDRIE, age ≥70 years, hypertension, diabetes, dialysis, cancer, immunosuppression, ischemic heart disease, atrial fibrillation, and complications such as hemorrhagic stroke, shock, and acute renal failure were independently associated with increased in-hospital mortality. Importantly, after multivariate adjustment, high-volume centers (≥20 IE cases/year) [hazard ratio (HR), 0.59; 95% confidence interval (CI), 0.50-0.70,
conclusionMortality outcomes of IE were determined by multiple factors, including patients' clinical characteristics, economic status, and center experience. Support for those with low economic status and establishment of well-experienced multidisciplinary teams may help to lower the risk of death in patients with IE.
