Remote dielectric sensing for pulmonary congestion assessment: current concepts and clinical perspectives.
Review in ESC heart failure, 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
Pulmonary congestion is a major determinant of symptoms, hospitalization, and prognosis in cardiovascular disease, yet its quantitative assessment remains challenging. Remote dielectric sensing is a non-invasive electromagnetic method that provides a quantitative estimate of pulmonary fluid content within ∼1 min. This narrative review summarizes the principles, validation, clinical interpretation, applications, and limitations of remote dielectric sensing. In a validation study of 46 hospitalized patients, including 28 with heart failure, remote dielectric sensing correlated with computed tomography-derived high-attenuation lung area (r = 0.65, P < .001). In a prospective study of 153 patients with heart failure, remote dielectric sensing correlated with lung ultrasound B-line count (r = 0.544); a threshold of 34.5% identified lung ultrasound-defined pulmonary congestion with an area under the curve of 0.748, sensitivity of 73.5%, and specificity of 70.2%. In 133 patients hospitalized with acute heart failure, with a median age of 78 years, 59% men, and a median left ventricular ejection fraction of 57%, an increase in remote dielectric sensing from admission to discharge was associated with all-cause death or heart failure rehospitalisation (adjusted hazard ratio 4.37, 95% confidence interval 1.13-16.81). In a proof-of-concept randomized trial of 100 patients hospitalized with acute decompensated heart failure, the primary endpoint occurred in 2% with remote dielectric sensing-guided care vs 20% with routine care (hazard ratio 0.094). Available evidence supports diagnostic validity and potential prognostic value, but external validation remains limited. Evidence that remote dielectric sensing-guided management improves clinical outcomes remains preliminary. Remote dielectric sensing should be considered a complementary component of multimodality congestion assessment.
