Dual Intracardiac Thromboses Associated With Dilated Coronary Sinus and Persistent Left Superior Vena Cava.

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
backgroundPersistent left superior vena cava (PLSVC) is associated with coronary sinus (CS) thrombosis. CASE SUMMARY: An 85-year-old woman with PLSVC presented with fever due to acute pyelonephritis. Transthoracic echocardiography revealed a mural thrombus within a dilated CS, with a contiguous free-floating thrombus extending into the right atrium. Anticoagulation with warfarin resulted in resolution of the free-floating component; however, the mural CS thrombus persisted. DISCUSSION: This case illustrates the interplay between congenital venous anomalies and transient hypercoagulability in thrombogenesis. Although contiguous thrombosis of the CS extending to the right atrium is rare, multiple coexisting prothrombotic conditions may contribute. A high index of suspicion and timely cardiac imaging are essential in patients with hypercoagulable state. TAKE-HOME MESSAGES: Patients with PLSVC may develop intracardiac thrombosis when hypercoagulation is present. Early imaging is crucial for prompt diagnosis, and appropriate anticoagulation management can be effective even in patients with a high bleeding risk.
