The S1Q3T3 Electrocardiographic Abnormality as a Result of Massive Empyema due to Pyogenic Liver Abscess: A Case Report.
Article in Clinical case reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
The S1Q3T3 pattern on the electrocardiogram is often associated with right heart strain in pulmonary embolism, pneumothorax, and acute lung diseases causing acute cor pulmonale. The S1Q3T3 pattern during acute massive empyema in the setting of a liver abscess has not been reported in theliterature. We present a case report of a 41-year-old Iranian female patient with a sudden onset chest pain, dyspnea, sinus tachycardia, and electrocardiography findings of S1Q3T3 pattern, who was revealed to have an expanding pyogenic pleural effusion as a result of trans-diaphragmatic extension of a liver abscess. The other causes of S1Q3T3 were excluded. The patient underwent the insertion of a chest tube to remove the pus. After chest tube insertion, the S1Q3T3 pattern resolved. Despite initial improvement, the patient developed complications, including pleural adhesions and lung collapse, and required a posterolateral thoracotomy with decortication. This resulted in dramatic clinical improvement. Rapidly expanding massive pyogenic pleural effusion can lead to the S1Q3T3 pattern on the electrocardiogram.
