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
backgroundDigitalis glycosides are employed for rate control of atrial fibrillation and treatment of heart failure. Previous studies suggested potential harmful effects of digitalis therapy. The aim of the present study was to assess the prevalence and potential impact of digitalis therapy on outcomes in patients with systolic failure who were implanted with an ICD- or CRT-ICD system. METHODS AND
resultsThe German Device Registry is a nationwide, prospective registry with a 1-year follow-up investigating 4384 patients receiving either ICD or CRT systems in 52 German centers. The present analysis focused on the presence of digitalis therapy in 3826 patients undergoing device implantation. Patients receiving digitalis therapy (n = 800) presented a more severely impaired left ventricular function, higher NYHA class, and an increased incidence of left bundle branch block. Consequently, the implantation of CRT systems was more common in this group. One-year mortality did not significantly differ between both groups (9.1% vs. 7.4%, p = 0.14). Similar results were obtained for the combined endpoint, including death, myocardial infarction, and stroke. ICD shock delivery (19.7% vs. 15.0%, p = 0.006) and device revision (11.4% vs. 7.5%, p < 0.004) were more common in digitalis-treated patients.
conclusionIn this study in patients undergoing ICD or CRT implantation, an association of digitalis therapy with an increased risk of device revision was observed. Of note, mortality or severe cardiovascular events did not differ between both groups. Furthermore, an increased risk of ICD shock delivery was observed in digitalis-treated patients.
