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: Cardiac injury in patients with severe polytrauma is often occult and carries a high mortality, making rapid and accurate diagnosis a significant clinical challenge. Case presentation: A 57-year-old Asian male was admitted with polytrauma and impaired consciousness for over 2 h after a fall from the 9th floor. Post-injury manifestations included confusion, restlessness, and active bleeding from multiple wounds. The initial diagnosis was polytrauma with traumatic hemorrhagic shock. Following initial resuscitation and thoracic endovascular aortic repair (TEVAR), he developed refractory hypoxemia and hemodynamic instability. Subsequent multimodal ultrasound revealed combined injuries: traumatic rupture of the right coronary sinus into the right atrium and right ventricle, multiple tears in the mid-portion of the atrial septum, and bidirectional shunt at the atrial level. The patient received comprehensive treatment, including TEVAR, mechanical ventilation, anti-infection therapy, maintenance of internal homeostasis, and nutritional support. Due to cardiopulmonary failure secondary to the cardiac injury, extracorporeal membrane oxygenation (ECMO) was initiated. Despite aggressive life-sustaining measures, the patient developed severe infection and multiple organ failure, precluding cardiac surgical intervention. He ultimately succumbed after the withdrawal of ECMO support. Conclusion: In the management of polytrauma, a high index of suspicion for occult cardiac injuries is essential. Multimodal echocardiography-comprising transthoracic echocardiography, transesophageal echocardiography, and agitated saline contrast echocardiography-serves as an efficient and precise bedside diagnostic toolkit. It not only enables rapid diagnosis of complex intracardiac injuries and hemodynamic assessment but also plays a crucial role in guiding advanced life support and developing effective treatment strategies. The early and systematic application of this approach may facilitate timely intervention for critically ill patients with polytrauma.
