1 · What the graph read from it

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.

2 · The registry

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

backgroundThe contemporary role of prophylactic anticoagulation following extensive anterior wall ST-segment myocardial infarction (STEMI) is unclear. METHODS AND

resultsWe evaluated anterior STEMI patients with left ventricle dysfunction (left ventricular ejection fraction ≤40%) ("high risk"), categorized by prophylactic warfarin use, within a regional STEMI. Patients with pre-existing atrial fibrillation were excluded. The primary outcome was an adjusted (for Global Registry of Acute Coronary Events risk score) 1-year composite of recurrent ischemia, stroke/transient ischemic attack/systemic embolism, or all-cause death. Of the 2032 STEMI admissions, 436 (21.5%) were high risk. After excluding 19 (4.4%) patients with definite left ventricle thrombus and 21 (4.8%) in-hospital deaths (2 had left ventricle thrombus), prophylactic warfarin was utilized in 236/398 (59.3%) high-risk survivors. Prescriptions were comparable across sex, but recipients were on average younger (58.5 years versus 64.0 years,

conclusionsA high utilization of prophylactic warfarin occurs in anterior STEMI patients with left ventricle dysfunction, yet appears to provide no additional benefit on the ischemic composite. The association with lower all-cause mortality, but higher bleeding, calls for an improved understanding of its role in high-risk STEMI.
