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
backgroundCentral nervous system (CNS) hemorrhage is a serious complication related to direct oral anticoagulant (DOAC) therapy. Current recommendations about re-initiation of anticoagulation treatment are limited to expert opinions. For this purpose, we analyzed the data of all consecutive DOAC patients with CNS hemorrhage, in whom DOACs were reinitiated.
methodsOver a 6-year period (2012-2018), all consecutive patients with CNS hemorrhage (subdural, subarachnoid, intracerebral, spinal), while receiving DOACs, were included in this observational single-center cohort study. DOAC therapy was reinitiated only in patients with well-controlled arterial hypertension and diabetes, as well as exclusion of vascular malformations and cerebral amyloid angiopathy. The composite primary endpoint comprised of recurrent CNS hemorrhage, ischemic stroke, and mortality; secondary endpoints were separate aforementioned outcomes.
resultsOf the 54 patients included, 18 died within a month of CNS hemorrhage. The average observational time was 590 days. DOACs were reinitiated in 13/36 patients (36%); of these patients, three died: none due to ischemic stroke or recurrent CNS bleeding. In 23 patients, anticoagulation was not reinitiated; of these patients, 10 died: three from recurrent CNS hemorrhage, one due to ischemic stroke, and six from causes unrelated to stroke.
conclusionsIn carefully selected patients, re-initiation of DOAC therapy did not increase the rate of both endpoints. Recommendations for DOAC re-initiation, which include hypertension and diabetes control, as well as treated vascular malformations, and excluded cerebral amyloid angiopathy, appear to be valid in clinical practice.
