Clinical utility of dynamic chest radiography as an auxiliary tool for atrial fibrillation detection in heart failure: a pilot study.
Article in BMC cardiovascular disorders, 2025. 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
backgroundDynamic chest radiography (DCR) can estimate haemodynamic parameters in patients with heart failure (HF). Atrial fibrillation (AF) often coexists with HF; however, owing to its sometimes paroxysmal nature and minimal or absent symptoms, many patients with AF remain undiagnosed. Additional tools for AF diagnosis may be beneficial; therefore, we evaluated the ability of DCR to distinguish patients with HF in sinus rhythm (SR) from those with AF.
methodsIn this small-sample pilot study, 20 patients with HF (median age, 67 years; males, 85%) underwent 12-lead electrocardiography and DCR on the same day. Aortic arch (Ao), right atrial (RA), right and left pulmonary artery (PA), and left ventricular (LV) apex pixel values (PVs) were measured. Seventeen patients were in SR and three demonstrated AF on 12-lead electrocardiography before DCR.
resultsThe PV and PV change rate waveforms of the Ao, RA, PAs, and LV apex were regular in SR and irregular with AF. The difference between patients in SR and those with AF was particularly clear in the LV apex PV change rate waveforms. In addition, the heart rates (HRs) of patients in SR and with AF could be calculated from the PV change rate waveforms and were similar to those calculated by 12-lead electrocardiography.
conclusionsDCR can detect AF in patients with HF and may be able to infer HR.
