Digoxin initiation after an acute heart failure episode and its association with post-discharge outcomes: an international multicenter analysis.

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
Digoxin is commonly used to treat acute heart failure (AHF), especially in patients with concurrent atrial fibrillation (AF). Nonetheless, there is little consensus about in which patients digoxin should be given, the proper time for digoxin initiation, and whether digoxin initiation is associated with improved outcomes. We investigated factors related to digoxin initiation after an episode of AHF and whether patients receiving digoxin presented better short-term outcomes. We analyzed digoxin-naïve AHF patients from a Spanish and Swiss database, who were dichotomized into cohorts based on their receipt of digoxin treatment at discharge. The relationship between digoxin initiation and 23 additional patient covariates, including chronic treatment, was investigated, as well as its association with 90-day combined adverse events (defined as all-cause death or AHF hospitalization). Of 13,105 patients (10,600/2505 from the Spanish/Swiss cohorts, respectively), the median (interquartile range) age was 83 (74.87) years, and 51% were women. Of these, 484 (3.7%) received digoxin at discharge, which was associated with AF, female sex, left ventricular ejection fraction (LVEF) < 50%, and coming from the Spanish cohort. Parameters inversely associated with receiving digoxin at discharge included some chronic treatments, diabetes mellitus (DM), and chronic kidney disease (CKD). Digoxin initiation was not association with 90-day adverse events, adjusted hazard ratio (aHR) = 0.939 (0.769-1.146), but there was an interaction for CKD, aHR = 1.390 (0.831-2.325) vs. 0.854 (0.682-1.183), p = 0.039, and for cohort pertinence, with higher risk in the Swiss cohort; aHR = 1.405 (0.827-2.386) vs. 0.862 (0.689-1.077), p = 0.046. Digoxin initiation after an AHF episode was more frequent in the Spanish cohort and was associated with certain patient characteristics (AF, female sex, reduced LVEF, no DM, no CKD), but had no effect on 90-day outcomes.
