Evaluation of thrombolytic treatment effect on frontal plane QRS-T angle in patients with acute pulmonary embolism : A novel marker of successful thrombolysis.

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
backgroundAcute pulmonary embolism (APE) patients with hypotension and/or shock should be evaluated for thrombolytic therapy, and hemodynamics often improves after thrombolytic therapy. Frontal plane QRS‑T (f[QRS-T]) angle, which is between the directions QRS axis and T axis, was described as a novel marker of ventricular repolarization heterogeneity. With right ventricular pressure overload, axis of heart may be affected and thrombolytic treatment may have an effect on this situation. This study aimed to investigate thrombolytic efficiency and effect on axis of heart by using f(QRS-T) angle.
methodA total of 61 APE patients treated with thrombolytics and 71 APE patients treated without thrombolytics were included. Clinical findings and electrocardiogram (ECG) at diagnosis were collected. Second ECGs were included for patients with thrombolytics after 24 h, without thrombolytics after 72 h on average.
resultsNo significant differences were observed with regard to gender, age, hypertension, diabetes and cardiovascular disease. In patients with thrombolytics, respiratory rate, heart rate and pulmonary artery systolic pressure were significantly higher; oxygen saturation (Sat O
conclusionRight ventricular pressure overload in APE has an effect on f(QRS-T). In thrombolytic treatment, the change of f(QRS-T) angle may be a marker of successful thrombolysis.
