Characteristics associated with left ventricular diastolic dysfunction and its prognostic implication in patients with sepsis: a prospective cohort study.
Article in Journal of anesthesia, 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
purposeTo identify risk factors and characteristics associated with left ventricular diastolic dysfunction and investigate its correlation with mortality in sepsis patients.
methodsA prospective cohort study was performed in sepsis patients between December 2022 and October 2023. Baseline characteristics, laboratory tests, treatments, echocardiographic results, and 28-day mortality were documented. Univariate and multivariate logistic regression analyses were conducted and a nomogram was constructed. Association between left ventricular diastolic dysfunction and 28-day mortality was analyzed.
resultsIn total, 117 patients with a mean age of 58.3 ± 16.5 years old and 63.3% men (74) were included. There were 75 (64.1%) and 42 (36.9%) patients with abnormal and normal diastolic dysfunction, respectively. Pneumonia, hematocrit, the ratio of E-wave peak velocity to A-wave peak velocity (E/A), ventricular septal early diastolic peak velocity of the mitral valve annulus (e'), and N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels were associated with ventricular diastolic dysfunction (P < 0.05). The nomogram constructed with these variables demonstrated high accuracy in predicting the occurrence of left ventricular diastolic dysfunction (area under the curve 0.938, sensitivity 83.8%, specificity 97.6%, Youden index 0.814). Left ventricular diastolic dysfunction could cause an increased 28-day mortality, with grade III diastolic dysfunction having the highest mortality rate (40.0%).
conclusionIn sepsis patients, a nomogram based on pneumonia, hematocrit, E/A, ventricular septal e', and NT-proBNP levels could accurately assess left ventricular diastolic dysfunction. Left ventricular diastolic dysfunction was associated with a high 28-day mortality, warranting further studies on the association between dysfunction severity and mortality risk.
