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: Ventricular septal rupture is a rare but devastating complication of acute myocardial infarction, frequently associated with cardiogenic shock and poor prognosis. Data regarding successful treatment strategies remain limited, and operative mortality significantly decreases when surgery can be delayed by 7-14 days. Case Summary: We present the case of a 61-year-old patient diagnosed with a posterior transmural myocardial infarction complicated by a large ventricular septal rupture. Right heart catheterization showed significant right ventricular (RV) overload, with elevated right atrial pressure (20 mmHg), right ventricular end-diastolic pressure (22 mmHg), and an elevated mean pulmonary artery pressure (44 mmHg). Due to the cardiogenic shock, we reduced the left-to-right shunt and achieved right ventricular unloading using a percutaneous microaxial flow pump (mAFP) with 5.5 L/min support as a bridge to surgical repair. This hemodynamic stabilization enabled a novel approach using triple patch reconstruction for post-infarction ventricular septal rupture. Discussion: This case highlights the effectiveness of early hemodynamic support with percutaneous mAFP in stabilizing patients with acute ventricular septal rupture, facilitating delayed surgical intervention, allowing time for infarct tissue to scar. The combined use of advanced surgical techniques and mechanical support may represent a key strategy in the management of this complex condition.
