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
Background: Aortic dissection is a severe and life-threatening condition that may involve both myocardial and vascular dysfunction. Conventional imaging parameters are limited in detecting subtle myocardial or vascular alterations associated with malperfusion. The aim of this study was to correlate echocardiographic myocardial deformation and vascular Doppler parameters with the Type-Entry-Malperfusion (TEM) classification in aortic dissection. Methods: This cross-sectional study included 114 patients with acute aortic dissection (mean age 56.6±11.8 years). Transesophageal echocardiography (TEE) and transthoracic echocardiography with speckle-tracking analysis were performed to evaluate conventional and myocardial deformation variables. Doppler ultrasound was used to assess descending aortic compliance. Results: Most patients (100%) presented type A dissection, predominantly with rupture in the ascending aorta (E1) or aortic arch (E2). Conventional echocardiographic parameters showed weak correlation with malperfusion categories (M0-M3). In contrast, global longitudinal strain (GLS) strongly correlated with myocardial malperfusion, particularly in E1/M1 (r=0.8333, P<0.0001), E1/M1 with bicuspid aortic valve (r=0.8872, P<0.0001), and E2/M2 (r=0.9018, P<0.0001). Myocardial biomarkers creatine kinase-MB (CK-MB) (r=0.8797, P<0.0001) and cardiac troponin I (cTnI) (r=0.6659, P<0.0001) also correlated with GLS. Doppler-derived pulsatility index (PI) correlated with smooth muscle myosin heavy chain (smMHC; r=0.8793, P<0.0001) and soluble elastin fragments (sELAF; r=0.7623, P<0.0001), indicating reduced vascular compliance. Conclusions: Integration of GLS and PI parameters with the TEM classification provides additional quantitative insight into myocardial and vascular injury in aortic dissection, supporting their potential prognostic value in surgical outcomes.
