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
introductionVeno-venous extracorporeal membrane oxygenation (ECMO) support has been used for respiratory insufficiency. Its role in blood oxygenation has been well documented. However, the effects on myocardial electrophysiology have not been studied in detail.
aimTo reveal the acute effects of extracorporeal support on new electrocardiography (ECG) parameters in patients with preserved left ventricular functions. MATERIAL AND
methodsThis retrospective study was conducted in three separate clinics. Sixteen consecutive patients under veno-venous ECMO for respiratory insufficiency who soon could be successfully weaned were analyzed. Immediately before and 2 hours after initiation of ECMO, ECG was performed. P wave, QT, QTc and T wave peak to end were measured and calculated from obtained surface 12-lead ECG.
resultsThere were statistically significant differences immediately before and 2 hours after initiation of ECMO treatment in the Tp-e interval and Tp-e/QTc ratio, the maximum QTc, minimum QTc, and QTc dispersion values, and P wave dispersion (
conclusionsAll atrial and ventricular repolarization parameters were decreased in patients with VV-ECMO support. Despite the limited role of ECMO in intractable arrhythmias, the findings of the study revealed that ECMO therapy for respiratory insufficiency may improve atrial ventricular depolarization and repolarization. Therefore, simple 12-lead surface ECG with new ECG parameters may be evaluated for better outcomes.
