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
Introduction: Massive pulmonary embolism (PE) is a life-threatening condition frequently associated with right ventricular (RV) strain, hypotension, and cardiac arrest. Recommended management includes IV alteplase for high-risk PE. However, evidence guiding higher thrombolytic doses during cardiac arrest remains limited and is rarely reported. We present a case of massive PE requiring an atypically high cumulative tPA dose administered during CPR, resulting in return of spontaneous circulation (ROSC). Case Description: A 38-year-old female with prior DVT and PE presented with syncope and left lower extremity edema. Imaging confirmed bilateral PE and DVT. She was found to be hemodynamically unstable and was treated with 100 mg IV tPA. This resulted in transient improvement, but she subsequently suffered a prolonged PEA arrest. During ACLS, there was confirmation of cardiac standstill on POCUS. A second bolus of 50 mg tPA was administered 29 min into the code, which led to sustained ROSC within 2 min. Despite maximal vasopressor and inotropic support, persistent shock and hypoxemia necessitated pulmonary angiography and attempted thrombectomy, which was aborted due to recurrent arrest. Catheter-directed thrombolysis with bilateral EKOS catheters was initiated, and by ICU Day 3, echocardiography revealed normalized RV function. Discussion: Massive PE causes acute RV failure and impaired pulmonary perfusion, which may limit thrombolytic delivery. Repeat tPA dosing during CPR may enhance clot penetration and improve outcomes. When systemic thrombolysis is insufficient, catheter-directed therapies can provide additional hemodynamic benefit. Adjunctive strategies including ventilatory optimization, pulmonary vasodilation, and neuroprotection were critical for the patient to achieving full recovery. Conclusion: Aggressive, multidisciplinary management, including repeat thrombolysis during arrest, can overcome traditionally poor prognostic indicators in massive PE and result in favorable neurologic outcomes.
